PI3 or Triiodophosphine is an inorganic compound. The bond formation in the molecule of Triiodophosphine can be understood by covalent bonding concept. So we will understand this by analyzing the PI3 lewis structure and facts related to it.
PI₃ (Phosphorus triiodide) has a trigonal pyramidal Lewis structure: a central phosphorus (P) atom with 5 valence electrons, forming single bonds with three iodine (I) atoms, each with 7 valence electrons. One lone pair on P creates <109.5° bond angle. Total of 32 valence electrons used. Electronegativity values: P (2.19), I (2.66), indicating polar bonds. The molecule is polar due to its asymmetrical shape and uneven electron distribution, despite the relatively small electronegativity difference.
PI3 lewis structure
Facts about PI3
The molar mass of Triiodophosphine 411.6 g/mol. In appearance, it exists as solid which has dark red color.
It’s melting point is around 61.2 degrees Celsius and boils at a temperature of 200 degrees Celsius. Its observed density is 4.18 g/cm3. Talking about the reactivity, it’s very when it comes to water. It reacts with water giving phosphorus acid and Iodane. Taking into account its preparation, it can be prepared by adding iodine to solution (white phosphorus + carbon disulfide).
Because this valence electrons are important to us as they are the ones which are involved in the process of bonding. In the structure we can see there are 4 atoms that are available for bonding, 3 atoms of the Iodine and one atoms belongs to Phosphorus. So now we will count the valence electrons taking into consideration the outer electronic configuration of the elements that are present in the structure of Triiodophosphine molecule. Phosphorus has 5 electrons as the valence electrons.
Now counting the contribution of iodine element atoms, there are 3 I atoms present. So the number of valence electrons contributed by I will be equivalent to the number 7, as there are 3 I atoms it will be 7×3=21 electrons. But the valency of iodine is one. It would rather give or take one electron and satisfy its octet. So in this molecule it each of the 3 iodine give their valence electrons. In this step we need to find the atom that has to be situated in the middle or center of the molecule.
So on what basis can we conclude which atom will come in the middle? We can predict by taking into account electronegativity of atoms under consideration. So the molecule with less electronegativity when compared to other atoms present in the molecule. The dots around each atoms means the valence electrons of that atom. Over here in this molecule phosphorus will be middle/central atom. Other atoms of iodine will be surrounding it. And the resulting bonds are single bonds.
PI3 lewis structure shape
According to valence shell electron pair repulsion theory lone pair have a great effect in influencing the shape of the molecule.
So in the molecule of Triiodophosphine, there is one lone pair. We know that lone pair prefers to maintain distance from the bonds. Hence the structure is caused to be of trigonal pyramidal shape.
What is the meaning of the term formal charge or what we understand by the term formal charge?
The word formal charge means that there is some amount of difference exiting in between the valence electrons (taking into account all the atoms) of the material that is being studied and the total number of electrons that are present in that material or substance. It is said that, while considering the formal charge concept when the bonding type of atoms are shared between the atoms while bonding, they are shared in an equal manner. Below is the formula by using which formal charge can be calculated:
Where V means the number of valence electrons that have been contributed by the atom of the molecule.
N indicates the total valence electrons which are as the unbound on the atom of our study.
B indicates all the total number of electrons that participate in bonding process by sharing electrons with the other atoms.
So in the molecule of Triiodophosphine, the formal charge is nil. There is zero formal charge.
Number of lone pairs in PI3 lewis structure
In the lewis structure of Triiodophosphine we can see there are 5 electrons with P as valence electrons and during the process of bonding P will be surrounded by 3 I atoms forming single bonds. We will see that one pair of electrons will remain unbonded, meaning will not participate in bonding. Hence the number of valence electrons in Triiodophosphine molecule will be one.
Hybridization in Triiodophosphine
We know that hybridization is the concept where in atomic orbitals combine to form hybrid atomic orbitals.
Coming to hybridization in the molecule of Triiodophosphine, it will be sp3 hybridization. Because in the molecule there are 3 bonding pairs and one pair is lone pair, for the accommodation of 4 pairs of electrons it has sp3 hybridization.
PI3 lewis structure resonance
PI3 Lewis structure octet rule
On the basis of octet rule the outer shell of the atoms must have 8 electrons, meaning a complete octet.
So in the molecule of phosphane the valency of phosphorus is 3, so it needs more 3 electrons in order to complete its octet. Hence it takes electrons from three iodine and forms three single bonds.
PI3 polar or nonpolar
As we can see there are three iodine atoms and one atom of phosphorus with one lone pair and three bonding pairs. This gives the molecule of Triiodophosphine a trigonal pyramidal shape. Causing it to have quite low polarity. Hence the molecule is observed to be non polar.
PI3 lewis structure bond angle
As the Triiodophosphine structure has a trigonal pyramid shape, the bond angle present in the molecule is equal to 102 degrees.
PI3 uses
It is an active component in preparing the compound phosphoric acid by treating PI3 with H2O.
Important reagent for the process of replacing the groups like hydroxyl by chlorine.
The PF5 Lewis structure refers to the arrangement of atoms and electrons in a molecule of phosphorus pentafluoride (PF5). In this structure, phosphorus is the central atom bonded to five fluorine atoms. The Lewis structure helps us understand the bonding and electron distribution within the molecule. It is represented by drawing the symbol for phosphorus in the center, surrounded by the symbols for fluorine atoms, with lines representing the bonds between them. The PF5 molecule has a trigonal bipyramidal shape, with three fluorine atoms in equatorial positions and two in axial positions. This arrangement allows for the optimal distribution of electrons.

Understanding Lewis Structures
What is a Lewis Structure?
A Lewis structure is a diagram that represents the arrangement of atoms and valence electrons in a molecule. It was developed by Gilbert N. Lewis in 1916 as a way to visualize chemical bonding. Lewis structures are also known as Lewis dot diagrams or electron dot structures.
In a Lewis structure, the valence electrons of an atom are represented by dots or lines. Each dot represents one valence electron, while each line represents a covalent bond. The goal of drawing a Lewis structure is to satisfy the octet rule, which states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration with eight valence electrons.
How to Draw a Lewis Structure
Drawing a Lewis structure involves several steps. Let’s take the example of Phosphorus pentafluoride (PF5) to understand the process.
Determine the total number of valence electrons in the molecule. For PF5, phosphorus (P) is in Group 5A and has 5 valence electrons, while each fluorine (F) atom has 7 valence electrons. Therefore, the total number of valence electrons in PF5 is 5 + (5 × 7) = 40.
Identify the central atom. In PF5, phosphorus is the central atom as it is less electronegative than fluorine.
Place the central atom in the center and connect it to the surrounding atoms with single bonds. In PF5, phosphorus is bonded to each fluorine atom.
Distribute the remaining electrons around the atoms to satisfy the octet rule. Start by placing lone pairs on the outer atoms (fluorine) and then distribute the remaining electrons on the central atom (phosphorus). Remember that each bond consists of two electrons.
Check if all atoms have achieved an octet or a stable electron configuration. In PF5, phosphorus has 10 valence electrons (5 bonds and 2 lone pairs), while each fluorine atom has 8 valence electrons (1 bond and 3 lone pairs). The total number of valence electrons is still 40.
If necessary, use double or triple bonds to satisfy the octet rule. In PF5, phosphorus can form a double bond with one of the fluorine atoms to achieve an octet.
By following these steps, we can draw the Lewis structure of PF5, which consists of a central phosphorus atom bonded to five fluorine atoms. The structure has one double bond and four single bonds, with each atom achieving an octet.
Lewis structures are useful in understanding the chemical bonding and molecular geometry of a compound. They provide insights into the electron pair geometry and molecular shape of a molecule. In the case of PF5, the electron pair geometry is trigonal bipyramidal, and the molecular shape is also trigonal bipyramidal.
It is important to note that Lewis structures are a simplified representation of molecules and do not account for the three-dimensional nature of molecules. To understand the actual shape of a molecule, we use the VSEPR (Valence Shell Electron Pair Repulsion) theory, which takes into account the repulsion between electron pairs to predict molecular shapes.
To understand the Lewis structure of PF5 (Phosphorus pentafluoride), we need to consider the valence electrons in PF5 and the octet rule. Phosphorus (P) is in Group 5A, so it has five valence electrons. Fluorine (F) is in Group 7A, so it has seven valence electrons. In PF5, there is one phosphorus atom bonded to five fluorine atoms.
To draw the Lewis structure for PF5, follow these steps:
Determine the total number of valence electrons: Phosphorus contributes 5 valence electrons, and each fluorine contributes 7 valence electrons. So, the total number of valence electrons in PF5 is 5 + (5 * 7) = 40.
Place the atoms in the structure: Phosphorus is the central atom, and the fluorine atoms are bonded to it. Since fluorine is more electronegative than phosphorus, it is more likely to be found on the outside of the structure.
Connect the atoms with single bonds: Each fluorine atom forms a single bond with the phosphorus atom. This accounts for 5 of the valence electrons.
Distribute the remaining electrons: After accounting for the single bonds, there are 35 valence electrons left. Place them as lone pairs around the fluorine atoms, ensuring that each atom has an octet (except for phosphorus).
Check for octets and adjust if necessary: Phosphorus does not have an octet yet. To complete its octet, move a lone pair from one of the fluorine atoms to form a double bond with phosphorus. This gives phosphorus a total of 8 valence electrons.
The final Lewis structure for PF5 is as follows:

Identifying the Correct Lewis Structure for PF5
To identify the correct Lewis structure for PF5, we need to consider the octet rule and the electron pair geometry. In PF5, the phosphorus atom is surrounded by five fluorine atoms, resulting in a trigonal bipyramidalelectron pair geometry.
The molecular shape of PF5 is also trigonal bipyramidal, with the phosphorus atom at the center and the fluorine atoms positioned around it. The bond angle between the phosphorus atom and the fluorine atoms is approximately 90 degrees.
Understanding the PF5 Lewis Dot Structure
In the Lewis dot structure of PF5, the phosphorus atom is represented by the letter P, and the fluorine atoms are represented by the letter F. The lines between the atoms represent covalent bonds, where electrons are shared between the atoms.
The Lewis dot structure of PF5 shows that there are no lone pairs of electrons on the phosphorus atom. All the valence electrons are either involved in bonding or shared between the atoms.
It is important to note that the PF5 molecule is nonpolar due to the symmetrical arrangement of the fluorine atoms around the central phosphorus atom. This means that the molecule does not have a positive or negative end, resulting in a balanced distribution of charge.
Detailed Analysis of PF5 Lewis Structure
Phosphorus pentafluoride (PF5) is a chemical compound composed of one phosphorus atom bonded to five fluorine atoms. To understand the structure of PF5, we can analyze its Lewis structure, which represents the arrangement of atoms and valence electrons in a molecule.
The shape of a molecule is determined by its electron pair geometry and molecular geometry. In the case of PF5, the electron pair geometry is trigonal bipyramidal, while the molecular geometry is also trigonal bipyramidal. This means that the five fluorine atoms are arranged around the central phosphorus atom in a trigonal bipyramidal shape.
Formal charges are used to determine the distribution of electrons in a molecule. In the Lewis structure of PF5, each fluorine atom is bonded to the phosphorus atom, resulting in a formal charge of zero for each atom. The phosphorus atom also has a formal charge of zero. This distribution of formal charges ensures that the molecule is stable.
Lone pairs are pairs of electrons that are not involved in bonding. In the Lewis structure of PF5, there are no lone pairs present on the central phosphorus atom. All the valence electrons of phosphorus are involved in bonding with the fluorine atoms. Therefore, PF5 does not have any lone pairs.
The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration with eight valence electrons. In the case of PF5, the phosphorus atom has five valence electrons, and each fluorine atom has seven valence electrons. By forming covalent bonds, the phosphorus atom shares its five valence electrons with the five fluorine atoms, resulting in a complete octet for each atom.
PF5 Lewis Structure Resonance
Resonance structures are different representations of a molecule that can be drawn by moving electrons within the molecule. However, in the case of PF5, resonance structures are not applicable as there are no multiple bonding possibilities or delocalized electrons.
PF5 Lewis Structure Bond Angle
The bond angle in PF5 refers to the angle between the phosphorus atom and the fluorine atoms. In a trigonal bipyramidal geometry, the bond angle between the equatorial fluorine atoms is 120 degrees, while the bond angle between the axial fluorine atoms and the phosphorus atom is 90 degrees. These bond angles contribute to the overall shape of the PF5 molecule.
PF5 Lewis Structure Electron Geometry
The electron geometry of PF5 is trigonal bipyramidal, as mentioned earlier. This geometry takes into account both the bonded atoms and the lone pairs, if present. In the case of PF5, there are no lone pairs, so the electron geometry is the same as the molecular geometry.
PF5 Lewis Structure Molecular Geometry
The molecular geometry of PF5 is also trigonal bipyramidal, as mentioned earlier. This geometry describes the arrangement of only the bonded atoms, excluding any lone pairs. The five fluorine atoms are symmetrically arranged around the central phosphorus atom, resulting in a trigonal bipyramidal shape for the PF5 molecule.
Hybridization in PF5
Understanding Hybridization
In order to understand hybridization in PF5 (phosphorus pentafluoride), let’s first discuss the concept of hybridization. Hybridization is a phenomenon in which atomic orbitals mix to form new hybrid orbitals. These hybrid orbitals have different shapes and energies compared to the original atomic orbitals. Hybridization occurs when an atom forms covalent bonds with other atoms.
In the case of PF5, phosphorus (P) is the central atom surrounded by five fluorine (F) atoms. To determine the hybridization of the central atom, we need to consider the valence electrons in PF5. Phosphorus has five valence electrons, and each fluorine atom contributes one valence electron, resulting in a total of ten valence electrons.
According to the octet rule, atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with eight valence electrons. In the case of PF5, phosphorus can achieve an octet by forming five covalent bonds with fluorine atoms.
To understand the hybridization in pentafluorophosphorane (PF5) in more detail, let’s analyze the molecular structure and bonding.
The Lewis dot diagram of PF5 shows that phosphorus is surrounded by five fluorine atoms, each sharing a single bond with the central phosphorus atom. This suggests that the phosphorus atom in PF5 is sp3d hybridized.
In sp3d hybridization, one s orbital, three p orbitals, and one d orbital from the phosphorus atom combine to form five sp3d hybrid orbitals. These hybrid orbitals are directed towards the five fluorine atoms, resulting in a trigonal bipyramidalelectron pair geometry.
The molecular shape of PF5 is also trigonal bipyramidal, with the five fluorine atoms positioned around the central phosphorus atom. The bond angle between the phosphorus atom and the fluorine atoms is approximately 90 degrees.
In terms of chemical bonding, the phosphorus atom forms covalent bonds with the fluorine atoms by sharing electron pairs. The electronegativity difference between phosphorus and fluorine is significant, resulting in polar covalent bonds. However, due to the symmetric arrangement of the fluorine atoms, the molecule as a whole is nonpolar.
It is important to note that PF5 can exhibit resonance structures due to the presence of lone pairs on the phosphorus atom. These resonance structures contribute to the overall stability of the molecule.
Polarity of PF5
Understanding Polarity
When it comes to understanding the polarity of molecules, it’s important to consider the arrangement of atoms and the distribution of electrons. In the case of PF5 (phosphorus pentafluoride), we can explore its polarity by examining its Lewis structure, molecular geometry, and the presence of any lone pairs.
Is PF5 Polar or Nonpolar?
To determine whether PF5 is polar or nonpolar, we need to analyze its molecular geometry. The Lewis dot diagram for PF5 shows that phosphorus (P) is surrounded by five fluorine (F) atoms. This molecule has a trigonal bipyramidalelectron pair geometry, with the phosphorus atom at the center and the fluorine atoms positioned around it.
According to the VSEPR (Valence Shell Electron Pair Repulsion) theory, the electron pairs in PF5 will arrange themselves in a way that minimizes repulsion. In this case, the three fluorine atoms are positioned in an equatorial plane, while the other two fluorine atoms are in axial positions. The bond angles between the phosphorus atom and the fluorine atoms are approximately 90 degrees for the axial positions and 120 degrees for the equatorial positions.
PF5 Lewis Structure: Polar or Nonpolar?
To determine the polarity of PF5, we need to consider the presence of any lone pairs on the central phosphorus atom. In the case of PF5, there are no lone pairs on the phosphorus atom. This means that all the electron pairs are involved in bonding with the fluorine atoms.
Since PF5 has a symmetrical arrangement of atoms and no lone pairs, the individual bond polarities cancel each other out. As a result, PF5 is a nonpolar molecule. The electronegativity difference between phosphorus and fluorine is not significant enough to create a dipole moment, leading to a nonpolar molecule.
By understanding the phosphorus pentafluoride structure and its molecular geometry, we can determine that PF5 is a nonpolar molecule. This knowledge of PF5’s polarity is essential in understanding its chemical bonding and behavior in various reactions.
Properties and Uses of PF5
Phosphorus pentafluoride (PF5) is a chemical compound that exhibits interesting properties and finds various practical applications. Let’s explore some key aspects of PF5, including its stability, molecular nature, and uses.
Is PF5 Stable?
PF5 is a stable compound under normal conditions. It is a solid at room temperature and pressure, appearing as a white crystalline powder. However, it is important to handle PF5 with care as it can react vigorously with water and other reactive substances.
Is PF5 a Molecular Compound?
Yes, PF5 is a molecular compound. It consists of a central phosphorus atom bonded to five fluorine atoms. The Lewis dot diagram for PF5 shows that phosphorus contributes one electron, while each fluorine atom contributes one electron, resulting in a total of 40 valence electrons. These electrons are involved in the formation of covalent bonds between phosphorus and fluorine.
Is PF5 Ionic?
No, PF5 is not an ionic compound. Ionic compounds typically involve the transfer of electrons between atoms, resulting in the formation of positive and negative ions. In the case of PF5, the sharing of electrons between phosphorus and fluorine atoms forms covalent bonds, where electrons are shared rather than transferred.

Fluorination Reactions: PF5 is commonly used as a fluorinating agent in organic synthesis. It can introduce fluorine atoms into organic molecules, leading to the formation of new compounds with desired properties. This is particularly useful in pharmaceutical and agrochemical industries.
Etching Agent: PF5 is utilized in the semiconductor industry as an etching agent. It can selectively remove certain materials from the surface of semiconductors, allowing for precise patterning and fabrication of electronic devices.
Catalyst: PF5 can act as a catalyst in various chemical reactions. It can enhance the rate of certain reactions without being consumed in the process. This property makes it valuable in industrial processes where increased reaction rates are desired.
Solvent: PF5 can serve as a solvent for certain reactions and processes. Its unique properties make it suitable for dissolving and stabilizing specific compounds, enabling efficient chemical transformations.

In chemistry, references are an essential part of understanding and verifying scientific information. They provide a way to access the sources that have been used to support the claims and findings presented in a particular study or article. By referring to these sources, readers can delve deeper into the subject matter and gain a more comprehensive understanding of the topic at hand.
When studying the structure and properties of phosphorus pentafluoride (PF5), several key concepts come into play. Understanding the Lewis dot diagram, molecular geometry, valence electrons, chemical bonding, octet rule, electron pair geometry, molecular shape, covalent bonds, and the bonding between phosphorus and fluorine are crucial to comprehending the behavior and characteristics of PF5.
To visualize the structure of PF5, we can draw a Lewis dot diagram. Phosphorus, with its atomic symbol P, is located at the center, while the five fluorine atoms, represented by the symbol F, are positioned around it. Each fluorine atom shares a covalent bond with the central phosphorus atom, resulting in a molecule with a trigonal bipyramidal shape. This arrangement allows for the optimal distribution of electron pairs and minimizes repulsion between them.
In terms of polarity, PF5 is a nonpolar molecule. This is due to the symmetrical arrangement of the fluorine atoms around the central phosphorus atom, resulting in a cancellation of dipole moments. Although the individual phosphorus-fluorine bonds are polar, the overall molecule does not possess a net dipole moment.
The VSEPR (Valence Shell Electron Pair Repulsion) theory helps us determine the molecular shape of PF5. According to this theory, the five electron pairs around the central phosphorus atom arrange themselves in a way that minimizes repulsion. Three of these electron pairs are bonding pairs, while the remaining two are lone pairs. The AXE notation, which stands for “A” representing the central atom, “X” representing the surrounding atoms, and “E” representing the lone pairs, can be used to describe the molecular geometry of PF5 as AX3E2.

In this article, we are going to have a closer approach towards facts related to the density of Dichloromethane.
The density of dichloromethane is observed to be 1.33 g/cm3. It is a liquid (colorless) which has a pleasant odor. It is a suitable solvent in many experiments. So in the following sections, we will study the facts and properties associated to it in detail.
Some facts about DCM
It is a polar compound and it’s synonym is methylene chloride.
It’s molecular weight is around 84.93 g/mol. In the structure of DCM, there exists one C atom, two H atoms, and two Cl atoms. It shape has tetrahedral geometry. Talking about its applications, in laboratories, it is commonly used in extraction (liquid-liquid). Also a very active component in paint removers.
Temperature influences density meaning, with an increase or decrease in temperature density can vary. Let us have a look at some facts and properties related to methylene chloride.
The observed boiling point is 39.75 degrees Celsius which makes it suitable to be separated from other liquids by using the fractional distillation technique. It’s freezing point is -95.14 degrees Celsius and its refractive index is 1.424 at a temperature of 20 degrees Celsius. So the density of dichloromethane in g/mL is 1.326 g/mL at a temperature of 20 degrees Celsius and 1.317 g/mL at a temperature of 25 degrees Celsius.
The observed density of dichloromethanein kg/m3 is 1322kg/m3 at a temperature of 20 degrees Celsius.
What is the density of dichloromethane?
The observed density of methylene chloride is 1.3266 g/cm3 at 20 degrees Celsius. At 90 degrees Celsius, the density is 0.93 g/cm3. It is clear from above that density of methylene chloride changes when there is a change in temperature.
Relative density of dichloromethane
What we understand by relative is it is the ratio of involving the density (of a substance) to the density of reference (the given reference substance/material).
Relative density is also referred to as specific gravity. Most of the time relative density is measured or calculated by using water as reference material. Relative density does not has any unit. When the relative density of a substance is less than 1 it will be less dense in comparison to the reference. When the relative density is more than one then we can say it is more dense then the reference. If equal to 1 then the density of both the substance under study and reference will have the same density.
Not necessarily every time water will be the reference, some other substance can also be used. If we consider water as a reference then the relative density of dichloromethane:
Relative density = density of dichloromethane / density of reference
= 1.3266 g/cm3/ 1 g/cm3
= 1.3266 (at a temperature of 20 degrees Celsius).
density of dichloromethane at different temperatures
At a temperature of 20 degrees Celsius the density of dichloromethane is 1.326 g/mL. At a temperature of 25 degrees Celsius the density is 1.317. At a temperature of 90 degrees Celsius the density is 0.93 g/mL.

Why is Ch2Cl2 denser then water?
The molecular weight of water is around 18 g/mol and the molecular weight of dichloromethane is 84 g/mol. We know that the molecules that are heavier will be more dense. Similar is the case with water and dichloromethane, DCM being heavier is more dense then water.
In this article we are going to study facts about phosphorus valence electrons and the compounds formed by them.
Phosphorus belongs to the 15 and 3rd period, basically it is a p-block element. Phosphorus valence electrons are equal to five. So in the further sectionswe will be discussing various phosphorus compounds and related facts.
Phosphorus in its elemental form is seen to exist in two forms namely white phosphorus and red phosphorus. Red phosphorus seems to be rare on earth due to its high reactivity. Many allotropes of phosphorus are seen to exist some of them include red, white, black, violet, etc. The white phosphorus is sometimes also referred to as yellow phosphorus because on exposure to light the white phosphorus turns into yellow color.
P4(Phosphorus)
White phosphorus
White phosphorus is also called as devil’s element, the reason being it has possibility to glow (green) in the dark.
It is very unstable hence its reactivity is quite high and is a volatile compound. As we can see in the structure there are 4 atoms of phosphorus that are arranged in a tetrahedral manner. It’s odor is similar to that of garlic which is very unpleasant. Its preferred to be stored under water due to its high reactivity.
It is produced or formed when white phosphorus is heated at a temperature of 250 degrees Celsius or sometimes when white phosphorus is exposed to light (sunlight). We can also say that red phosphorus is an intermediate (phase) in between the white phosphorus and red phosphorus. The freshly prepared red phosphorus is seen to be very reactive and can ignite at a temperature of 300 degrees Celsius.
This compound is produced is formed when the red phosphorus is heated at a temperature of 550 degrees Celsius. It is also known as Hittorf’s phosphorus and alpha metallic phosphorus. This compound is known for its properties like electronic and optoelectronic properties.
Black phosphorus
Among all the phosphorus compounds Black phosphorus is seen to be less reactive. It’s synonym is beta metallic phosphorus. In structure it is similar to graphite. It is produced when white phosphorus is heated at very high temperature and pressure.
Talking about the bonding in p4 molecule as we can see that there are 4 phosphorus atoms in the structure.
The valence electrons in phosphorus are 5. Since 4 phosphorus atoms are present the total phosphorus valence electrons will be 5×4=20 electrons. What happens is the phosphorus atoms are placed in tetrahedral manner and then they are linked such that the valency of each of the phosphorus atom is satisfied.
Phosphorus valence electrons configuration
The valence electrons in phosphorus are 5. The valence electrons configuration is 3s2 3p3.
Phosphorus Valence Electrons charge
We know that there are 5 valence electrons in phosphorus and it is a non metal. It is seen to have more affinity towards electrons hence it will prefer gaining electrons rather then losing electrons.
So it needs three more electrons to complete its octet, therefore it will gain three electrons and satisfy its valency. Hence the charge on phosphorus valence electrons is -3.
Phosphorus valence electrons and valency
The phosphorus valence electrons are 5. What we understand is by the term valency is its capacity to gain or lose electrons in order to acquire a complete octet. So the valency of phosphorus is equal to 3.
The SBr4 Lewis structure refers to the arrangement of atoms and electrons in a molecule of sulfur tetrabromide. Sulfur tetrabromide is a chemical compound composed of one sulfur atom and four bromine atoms. The Lewis structure helps us understand the bonding and electron distribution within the molecule. In this structure, the sulfur atom is in the center, surrounded by four bromine atoms. Each bromine atom forms a single bond with the sulfur atom, resulting in a tetrahedral shape. The Lewis structure of SBr4 is crucial in predicting the molecule’s properties and understanding its chemical behavior.

Basics of Lewis Structures
Lewis structures are a visual representation of the arrangement of atoms and valence electrons in a molecule. They provide valuable insights into the bonding and geometry of molecules. In this article, we will explore the fundamentals of Lewis structures and how to draw them.
What is a Lewis Structure?
A Lewis structure, also known as a Lewis dot structure or electron dot structure, is a diagram that shows the bonding and non-bonding electrons in a molecule. It was developed by Gilbert N. Lewis in 1916 as a way to understand chemical bonding.
Lewis structures are based on the concept of valence electrons, which are the electrons in the outermost energy level of an atom. These electrons play a crucial role in determining the chemical properties and reactivity of elements.
How to Identify a Lewis Structure
To identify a Lewis structure, you need to know the number of valence electrons in the atoms involved. Valence electrons can be determined by looking at the group number of the element in the periodic table. For example, sulfur (S) is in group 16, so it has 6 valence electrons.
Once you know the number of valence electrons, you can determine the Lewis structure by following a set of steps.
Steps to Draw a Lewis Structure
Determine the total number of valence electrons in the molecule by adding up the valence electrons of each atom.
Identify the central atom, which is usually the least electronegative element or the one with the highest valence.
Connect the central atom to the surrounding atoms using single bonds.
Distribute the remaining electrons around the atoms to satisfy the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration.
If there are still remaining electrons, place them as lone pairs on the outer atoms.
Check if all atoms have achieved an octet or a duet (for hydrogen). If not, form multiple bonds by converting lone pairs into bonding pairs.
Finally, make sure the total number of valence electrons used matches the initial count.
Lewis Structure for Beginners
Drawing Lewis structures can be challenging at first, but with practice, it becomes easier. Let’s take an example of sulfur tetrabromide (SBr4) to illustrate the process.
Identify the central atom:
In SBr4, sulfur (S) is the central atom.
Connect the central atom to the surrounding atoms:
Place a single bond between sulfur (S) and each bromine (Br) atom.
Distribute the remaining electrons:
Start by placing lone pairs around the outer atoms (bromine) until they have an octet. Then, distribute the remaining electrons on the central atom.
Check if all atoms have achieved an octet:
In the case of SBr4, all atoms have achieved an octet, and the total count of valence electrons used is 34.
By following these steps, you can draw the Lewis structure for SBr4. It is important to note that Lewis structures are not always unique, and resonance structures may exist for certain molecules.
Remember, Lewis structures provide a simplified representation of molecular bonding and geometry. They help us understand the electron distribution and predict the properties of molecules.
So, the next time you encounter a molecule like SBr4, you can confidently draw its Lewis structure and gain insights into its molecular shape, bonding, and electron cloud.
Detailed Analysis of SBr4 Lewis Structure
How to Draw Lewis Structure for SBr4
To draw the Lewis structure for SBr4 (sulfur tetrabromide), we need to determine the total number of valence electrons in the molecule. Sulfur (S) is in Group 6 of the periodic table and has 6 valence electrons, while each bromine (Br) atom has 7 valence electrons. Multiplying the number of bromine atoms (4) by the number of valence electrons per bromine atom (7) gives us a total of 28 valence electrons. Adding the 6 valence electrons from sulfur, we have a total of 34 valence electrons for SBr4.
Next, we arrange the atoms in a way that satisfies the octet rule, where each atom (except hydrogen) wants to have 8 electrons in its outermost shell. Since sulfur is the central atom in SBr4, we place it in the center and surround it with the four bromine atoms. Each bromine atom forms a single bond with sulfur, using 2 valence electrons. This accounts for 8 electrons (4 bonds x 2 electrons per bond).
After forming the single bonds, we distribute the remaining electrons as lone pairs to satisfy the octet rule for each atom. In this case, we have 26 electrons left to distribute. We place 6 electrons (3 lone pairs) around each bromine atom, and the remaining 14 electrons (7 lone pairs) around the sulfur atom.
The Lewis structure of SBr4 reveals that it has a tetrahedral molecular geometry. The central sulfur atom is surrounded by four bromine atoms, forming a regular tetrahedron. The bond angles between the sulfur atom and the four bromine atoms are approximately 109.5 degrees, which is the ideal bond angle for a tetrahedral arrangement.
SBr4 Lewis Structure Formal Charge
To determine the formal charge of each atom in the SBr4 Lewis structure, we compare the number of valence electrons an atom has in its neutral state to the number of electrons it actually has in the Lewis structure. The formal charge is calculated using the formula:
In SBr4, the sulfur atom has 6 valence electrons and is surrounded by 3 lone pairs and 4 bonding electrons. Plugging these values into the formula, we find that the formal charge on sulfur is 0.
Each bromine atom in SBr4 has 7 valence electrons and is surrounded by 3 lone pairs and 2 bonding electrons. Calculating the formal charge for bromine, we get -1. Therefore, each bromine atom in SBr4 carries a formal charge of -1.
SBr4 Lewis Structure Lone Pairs
In the Lewis structure of SBr4, each bromine atom has 3 lone pairs of electrons, while the sulfur atom has 3 lone pairs as well. These lone pairs contribute to the overall electron cloud around the atoms and affect the molecule’s shape and properties.
SBr4 Lewis Structure Resonance
Resonance structures occur when multiple valid Lewis structures can be drawn for a molecule by moving electrons. However, in the case of SBr4, resonance structures are not applicable as there is no possibility of electron movement between atoms.
SBr4 Lewis Structure and the Octet Rule
The Lewis structure of SBr4 satisfies the octet rule for each atom, meaning that each atom has a full outer shell of 8 electrons (except hydrogen, which follows the duet rule). The sulfur atom has 8 electrons around it (6 from the lone pairs and 2 from the bonding electrons), and each bromine atom has 8 electrons around it (6 from the lone pairs and 2 from the bonding electrons). This arrangement ensures that all atoms in SBr4 have a stable electron configuration.
In conclusion, the Lewis structure of SBr4, with its tetrahedral molecular geometry and satisfying the octet rule, provides valuable insights into the bonding and electron distribution within the molecule. The presence of lone pairs and the formal charges on the atoms further contribute to the overall understanding of SBr4’s chemical properties.
Advanced Concepts Related to SBr4 Lewis Structure
Sulfur tetrabromide (SBr4) is a chemical compound composed of one sulfur atom and four bromine atoms. Understanding the advanced concepts related to its Lewis structure can provide insights into its molecular geometry, hybridization, and polarity.
SBr4 Hybridization
To determine the hybridization of SBr4, we need to consider the number of valence electrons in sulfur and the number of bonding and lone pairs around the central atom. Sulfur has six valence electrons, and each bromine atom contributes one electron, resulting in a total of ten valence electrons for SBr4.
In the Lewis dot structure of SBr4, sulfur forms four single bonds with the four bromine atoms. This suggests that sulfur undergoes sp3 hybridization, where one 3s orbital and three 3p orbitals hybridize to form four sp3 hybrid orbitals. These hybrid orbitals then overlap with the bromine’s p orbitals to form four sigma bonds.
SBr4 Lewis Structure Molecular Geometry
The molecular geometry of SBr4 can be determined using the Valence Shell Electron Pair Repulsion (VSEPR) theory. In this theory, electron pairs around the central atom repel each other and arrange themselves in a way that minimizes repulsion.
In the case of SBr4, there are four bonding pairs and no lone pairs around the central sulfur atom. According to VSEPR theory, this arrangement corresponds to a tetrahedral electron pair geometry. The four bromine atoms are positioned at the four corners of a tetrahedron around the central sulfur atom.
Is SBr4 Polar or Nonpolar?
To determine the polarity of SBr4, we need to consider the molecular geometry and the electronegativity difference between the atoms. The electronegativity of sulfur is 2.58, while bromine has an electronegativity of 2.96.
Since SBr4 has a tetrahedral electron pair geometry, the four bromine atoms are symmetrically arranged around the central sulfur atom. This symmetrical distribution of electron pairs results in a nonpolar molecule, despite the slight electronegativity difference between sulfur and bromine.
In conclusion, the advanced concepts related to SBr4 Lewis structure, including hybridization, molecular geometry, and polarity, provide a comprehensive understanding of this compound’s properties. The sp3 hybridization of sulfur, tetrahedral electron pair geometry, and nonpolar nature contribute to the overall behavior of SBr4 in chemical reactions and interactions.

The bond angles between the sulfur and bromine atoms are approximately 104.5 degrees.
In terms of electron pair geometry, SBr2 has a trigonal planar electron pair geometry. This means that there are three electron pairs around the central sulfur atom, including two bonding pairs and one lone pair. The presence of the lone pair contributes to the bent shape of the molecule.

Frequently Asked Questions
1. Why is SBr2 nonpolar?
SBr2 is nonpolar because it has a linear molecular geometry. This means that the bromine atoms are located directly across from each other, leading to a cancellation of their dipole moments. As a result, the molecule as a whole does not have a net dipole moment, making it nonpolar.
2. How can I identify a Lewis structure?
A Lewis structure can be identified by its representation of atoms, showing both the atomic symbols and the bonds between them. It also includes lone pairs of electrons. The central atom is usually the one with the lowest electronegativity or the one that can form the most bonds.
3. What are the steps to work out a Lewis structure?
The steps to work out a Lewis structure are:
– Identify the total number of valence electrons in the molecule.
– Choose the central atom (usually the one with the lowest electronegativity or the one that can form the most bonds).
– Draw single bonds between the central atom and the surrounding atoms.
– Distribute the remaining electrons as lone pairs, starting with the outer atoms.
– If there are still electrons left, place them on the central atom.
– Check if the structure follows the octet rule. If not, form double or triple bonds as necessary.
4. What is the Lewis structure of F3-?
The Lewis structure of F3- consists of three fluorine atoms bonded to a central atom with a negative charge. Each fluorine atom has six electrons in its valence shell, and the central atom has one, making a total of 10 electrons. The central atom forms a single bond with each fluorine atom and has one lone pair.
5. Is CBr4 polar or nonpolar?
CBr4 is a nonpolar molecule. This is because it has a tetrahedral shape, which allows the dipole moments of the C-Br bonds to cancel each other out. Therefore, there is no net dipole moment, making CBr4 nonpolar.
6. Does CBr4 have a dipole moment?
No, CBr4 does not have a dipole moment. Although the C-Br bonds are polar due to the difference in electronegativity between carbon and bromine, the molecule’s tetrahedral shape causes these dipole moments to cancel each other out. Therefore, CBr4 as a whole does not have a net dipole moment.
7. What is the molecular geometry of SBr4?
The molecular geometry of SBr4 is seesaw. This is because it has five regions of electron density (four bonding pairs and one lone pair) around the central sulfur atom.
8. How can I find the hybridization from a Lewis structure?
The hybridization of an atom in a molecule can be determined from its Lewis structure by counting the number of atoms bonded to it (single, double, or triple bonds each count as one) and the number of lone pairs of electrons. The sum of these two numbers determines the hybridization: two gives sp, three gives sp2, four gives sp3, five gives sp3d, and six gives sp3d2.
9. What is the shape of the CBr4 Lewis structure?
The shape of the CBr4 Lewis structure is tetrahedral. This is because there are four regions of electron density (four bonding pairs) around the central carbon atom, which arrange themselves to minimize repulsion.
10. Is SBr4 polar or nonpolar?
SBr4 is a polar molecule. Although the S-Br bonds are polar, the molecule’s seesaw shape does not allow these dipole moments to cancel each other out completely. Therefore, SBr4 has a net dipole moment and is polar.
In this article, we are going to analyze the SBr6 lewis structure and various facts about it.
SBr6 or sulfur bromide is an inorganic compound which form by covalent bonding. So the bonding in sulfur bromide can be explained by the concept oflewis dot structure. So we will study SBr6 lewis structure in detail and various facts related to it in the following sections.
Some facts about SBr6
The observed molecular weight of sulfur bromide or sulfur hexabromide is around 511.5g.
It is one of the compounds of sulfur. We know that sulfur does not have any characteristics odor and also it is considered to be a very poor conductor of electricity and heat. It can exist in 3 allotropic forms namely rhombic sulfur, monoclonal sulfur, and plastic sulfur. The melting points of the allotropes are 112 degrees Celsius, 119 degrees Celsius respectively and there is no observed sharp melting point for plastic sulfur.
So it’s compounds would also exhibit somewhat similar kind of properties.
How to draw lewis structure for SBr6?
We must know the number of valence electrons in order to draw the structure. So the number of valence electrons in sulfur hexabromide: According to the formula there is one sulfur atom and six bromine atoms in the structure.
The number of valence electrons in sulfur are 6 and in bromine, there are 7 (as there are six bromine atoms in the molecule, the number of valence electrons will be 7×6=42 electrons). So total number of valence electrons in the molecule will be 6+42=48 electrons.Now we have to identify the atom that has to be placed in the center, so the central atom is the one that has the least electronegativity.
In this molecule, sulfur will be the central atom, and the rest(bromine) atoms will be the surrounding ones. As we can see, the dots around the atoms represent the number of valence electrons.
So the dots are placed in a manner that it satisfies the valency of the bonding atoms. Hence in each bond fluorine and antimony both contribute one electron each and thus satisfy each others valency. As only one pair of electrons is involved in the formation of the bond the resulting bond is a single bond. We can see that there are more electrons with the sulfur atoms the reason is because it is an exception.
SBr6 Lewis Structure shape
Taking into account the SBr6 lewis structure shape, it has an octahedral shape.
So how can we say or conclude that it has an octahedral shape? In an octahedral type of geometry, one atom is at the center and six more atoms are attached to it. The observed bond angle in this kind of geometry is around 90 degrees. This octahedral geometry concept was developed by sir Alfred W. So we can say the coordination number of the central atom is 6.
A formal charge on any atom is the difference in between number of valence electrons (includes every atom) and the associated number of electrons. It is assumed by formal charge that any electrons that are shared are shared equally between two bonding atoms. Formal charge is calculated by using the below formula:
Where, the term V means number of valence electrons contributed by the atom (as though isolated from a molecule).
The term N means number of unbound (valence electrons) on an atom that is being considered of molecule.
The term B means the total number of electrons that are shared by bonds with the other atoms in molecule.
So, considering the molecule of SBr6, hence the formal charge on the entire molecule will be zero.
SBr6 Lewis structure lone pairs
A lone pair means pair of valence electrons which are not shared during the process of bonding.
They are meant to be found in outermost (electron) shell of the atoms. We can say that the number of lone pairs around any atom when added to the number of electrons participating in bonding equals to the number of valence electrons in the atom. The concept of lone pair is of VSEPR (valence shell electron repulsion theory). Coming to the molecule of SBr6 there is no lone pair present.
SBr6 hybridization
Hybridization is the concept/process of mixing the atomic orbitals in order to form new orbitals (hybrid) which have much different shape, energy.
(Hybrid orbital formation is possible when the atomic orbitals have comparable kind of energies). This formed (hybrid) orbitals can be used to explain properties like atomic bonding and geometry (molecular). The hybridization in SBr6 molecule is sp3d2. At the ground state, there are two electrons in the 3s orbitals and three electrons in 3p orbitals. And then the new hybrid orbitals are formed with six bromine atoms.
SBr6 lewis structure resonance
SBr6 Lewis structure octet rule
According to the octet rule, an atom wants to obtain a completely filled octet. Meaning there should be total 8 electrons present in the outermost shell. This is the reason Sulfur forms single bonds by sharing one electron pair each with 6 bromine atoms. But we can see there are more electrons with sulfur indicating this compound to be an exception.
In this article, we are going to analyze how to draw SbF3 and various facts about it.
SbF3 or antimony trifluoride is an inorganic compound which has ionic type of bonding. So the bonding can be explained by the concept of lewis dot structure. So we will study thesbf3 lewis structure in detail and various facts related to it in the following sections.

Taking into account its applications it is usually used as a reagent (fluorination) in chemistry (organic). This was first discovered by Fredric J.E Swarts in the year 1892 (as to how it can be used for the conversion of chlorides into fluorides). Where antimony trifluoride was treated with chlorine which gave or produced trifluorodichloride. This is the Swarts reaction which is usually employed in the production of compounds of organofluorine.
How to draw lewis structure for SbF3?
We must know the number of valence electrons in order to draw the structure. So the number of valence electrons in antimony trifluoride.
According to the formula there is one antimony and three fluorine atoms in the structure. The number of valence electrons in antimony are 5 and in fluorine, there are 7 (as there are three fluorine atoms in the molecule, the number of valence electrons will be 7×3=21 electrons). So total number of valence electrons in the molecule will be 5+21=26 electrons. Now we have to identify the atom that has to be placed in the center, so the central atom is the one that has the least electronegativity.
In this molecule, antimony will be the central atom, and the rest (fluorine) atoms will be the surrounding ones. As we can see, the dots around the atoms represent the number of valence electrons. So the dots are placed in a manner that it satisfies the valency of the bonding atoms. Hence in each bond fluorine and antimony both contribute one electron each and thus satisfy each others valency. As only one pair of electrons is involved in the formation of bond the resulting bond is a single bond.
SbF3 lewis structure shape
Taking into account the SbF3 lewis structure shape, it has a trigonal pyramidal shape.
So how can we say or conclude that it has trigonal pyramidal? What we mean by trigonal pyramidal geometry is that one of the atom is placed at the apex and the remaining three are placed at the corners of the trigonal base which resembles a tetrahedron. So in the structure. There is one antimony atom and three fluorine atoms, the antimony is the central atom and the rest are the fluorine atoms.
So it’s coordination number is 3. The bond angle ranges from 90 degrees to somewhere around 109.5 degrees.
SbF3 Lewis structure formal charge
A formal charge on any atom is the difference in between number of valence electrons (includes every atom) and the associated number of electrons. It is assumed by the formal charge that any electrons that are shared are shared equally between two bonding atoms. The formal charge is calculated by using the below formula:
Where, the term V means number of valence electrons contributed by the atom (as though isolated from a molecule).
The term N means number of unbound (valence electrons) on atom that is being considered of molecule.
The term B means the total number of electrons that are shared by bonds with the other atoms in molecule.
So, considering the molecule of SbF3 the formal charge on Sb is zero and on Fluorine is also zero. Hence the formal charge on the entire molecule will be zero.
SbF3 Lewis structure lone pairs
A lone pair means pair of valence electrons which are not shared during the process of bonding.
They are meant to be found in the outermost (electron) shell of the atoms. We can say that the number of lone pairs around any atom when added to the number of electrons participating in bonding equals to the number of valence electrons in the atom. The concept of lone pair is of VSEPR (valence shell electron repulsion theory). Coming to the molecule of SbF3 there is one lone pair present.
SbF3 hybridization
Hybridization is the concept/process of mixing the atomic orbitals in order to form new orbitals (hybrid) which have much different shape, energy.
(Hybrid orbital formation is possible when the atomic orbitals have comparable kind of energies). This formed (hybrid) orbitals can be used to explain properties like atomic bonding and geometry (molecular). The hybridization in SbF3 molecule is sp3.
At the ground state, there are two electrons in the 5s orbitals and three electrons in 5p orbitals. And then the new hybrid orbitals are formed with three fluorine atoms.
SbF4 lewis structure resonance
SbF3 Lewis structure octet rule
According to the octet rule, an atom wants to obtain a completely filled octet. Meaning there should be total of 8 electrons present in the outermost shell. This is the reason Sb forms single bonds by sharing one electron pair each with 3 fluorine atoms.That is the reason atoms share their valence electrons, so that they can have a complete octet meaning their valency is satisfied.
In this, article we are going to study examples of various covalent bond types of atoms.
A covalent bond is usually formed between the atoms that belong to non- metallic elements. Do a covalent bond should necessarily have a difference in their electronegativities. So in order to understand properties and facts related to this we will study covalent bond types of atoms in detail.
H2O atoms example of covalent bond types of atoms
As we can see in the structure of a water molecule it contains one hydrogen atom and two hydrogen atoms which form a covalent bond. The covalent bonding of these atoms can be explained by the lewis dot structure concept.
We know that the oxygen atom has 6 valence electrons and hydrogen has one valence electron (since there are two hydrogen atoms, the total hydrogen valence electrons will be 1×2=2 electrons). The total valence electrons will be 6+2=8 electrons. One electron pair is shared between each of the two hydrogen atoms and the oxygen atom and in this way, the valency of both atoms is satisfied by forming a covalent bond. H2O is an inorganic compound which has polarity. This particular compound is colorless and does not have any odor. Also, H2O is the only compound which can exist in 3 forms (solid, liquid, and gas).
Talking about its magnetism it is diamagnetic in nature. It’s freezing point is zero degrees Celsius and boils at a temperature of 100 degrees Celsius. Due to polar nature, it can exhibit hydrogen bonding. Taking into account the reactivity of H2O molecule, elements ( metallic, usually the alkali and alkaline earth metals e.g. sodium, potassium, calcium, Lithium, etc.) which are seen to be more electropositive in comparison to hydrogen have the ability to displace hydrogen in H2O molecule. And they for. Hydroxides and release hydrogen. At higher temperatures, carbon is seen to react with steam and form hydrogen and carbon monoxide.
The structure of ethanol has two carbon atoms, 6 hydrogen atoms, and one oxygen atom which form a covalent bond. The covalent bonding these atoms can be explained by the lewis dot structure concept.
We know that a carbon atom has 4 valence electrons (since there are two carbon atoms, the total carbon valence electrons will be 4×2=8 electrons) and hydrogen has one valence electron (since there are six hydrogen atoms, the total hydrogen valence electrons will be 1×6=6 electrons).

In this article we are going to study various facts related to cysteine structure in detail.
Cysteine is said to be a non essential amino acid that contains sulfur. The importance of cysteine is that it is very important synthesis of protein, various metabolic related functions and detoxification. It’s IUPAC name is (2R)-2-amino-3-sulfanypropanoic acid.
Facts about cysteine structure:
Cysteine is seen to exist in zwitterion form. It was first discovered by Louis N.V and Pierre J.R in the year 1806. In appearance it is white crystalline (powder) and has a melting point of 240 degree Celsius.
Discussing about its structure in brief, it has one carbon atom which is an alpha carbon to which a alpha carboxylic acid and alpha amino group is attached. As we can see in the diagram there is one hydrogen that is attached to alpha carbon. The NH3 group is seen to be common in almost all amino groups.
The cysteine structure has thiol side chain (side group -R) which is often seen to participate in the enzymatic kind of reactions as nucleophile. The only difference that exists in the structure of amino acids is the side chin or side group. UGC and UGU are the amino acids that code for cysteine. Most of the times the structure of cysteine is L-cysteine.
It has been observed that cysteine is not stable in air. Hence usually in proteins it is seen to exist as cystine (it forms a disulfide bond in between residues of 2 cysteine).
It is very carefully protected in protein to enhance its stabilizing activity of structures of high order in a protein. Cysteine is considered as a very powerful antioxidant and has anti-aging properties. But one problem with this is that cysteine tends to be absorbed in cells and there it is unable to exhibit the antioxidant property. Hence to overcome this limitation NAC (N-acetyl cysteine) is being used. When cysteine is used as food additive, the E number that it has is E920.
Product of cysteine is cystine when 2 cysteine come in close proximity with each other two sulfur donate hydrogen and form disulfide bond, this is how a cystine molecule is formed. But cysteine and cystine differ in properties.It’s molecular weight is 121.16 g/mol. In the below section we’ll get a clear view on cysteine structure and its functionality.
Cystine
It has been observed that cystine is less soluble in comparison to cysteine. Seen to be more stable and is formed from the process of oxidation of the cysteine. Considered to be semi essential and can be essential amino acid at times. It is not absorbed easily by body.
It has been observed that cystine is more soluble in comparison to cystine. Seen to be less stable and is formed from the amino acids methionine and serin. Considered to be non essential amino acid. It is easily absorbed body. It is seen to be soluble in water and also dissolves in ethanol at a temperature around 19-20 degree Celsius.
Sources of cysteine:
Animal source:Meat, fish, egg, etc.
Vegetarian source: sprouts, lentils, garlic, etc.
Conjugationfacts about cysteine structure:
Conjugation based on cysteine target the sulfur (thiol) atoms (in side chain) for the nucleophilic type of reactions such as with Michael acceptor like maleimides or it can also be electrophiles like haloacetamides. The chemistry of thiol and maleimide is of great interest as the reactions take place at both acidic as well as basic type of conditions (pH 6 to 8).
