Electron dot structure gives idea about the planer structure of a molecule. This article will discuss about sh2 lewis structure and the method of drawing it.
Outer orbit electrons are shown in the sh2 lewis structure. So from this lewis structure we can conclude the facts about the hybridization, shape and other things about the molecule.
How to draw lewis structure for SH2
SH2 Lewis structure gives information about outer most orbit electrons of the involved atoms. These electrons are responsible for chemical properties of the molecule.
To drawHydrogen Sulfide lewis structure, the atomic symbols of atoms that are ‘S’ for Sulfur and ‘H’ for Hydrogen are written. The outer orbit electrons of an atom are shown by dot symbols around that particular atom in the sh2 molecule.
Sulfur is a ‘group 16’ element and Hydrogen is a ‘group 1’ element in the Periodic table.
Electronic configuration of Sulfur: [Ne] 3s2 3p4. Electronic configuration of Hydrogen: [Ne] 1s1. So outer orbit electrons of Sulfur atom are six and that of Hydrogen atom is one.
Total number of the outer orbit electrons are {6 + (1×2)} =8. Hence four pairs of electrons take part in SH2 molecule formation.
Less electronegative atom becomes the central atom in the molecule. So Hydrogen atom should be the central atom. But it should have minimum two electrons to be a central atom which is not possible for Hydrogen atom. Sulfur becomes the central atom in the SH2 molecule.
Two Hydrogen atoms form sigma bonds (single bond) with Sulfur atom. Four electrons (two pairs of electrons) take part in bond formation. Central atom Sulfur has four unshared electrons over it.
Straight lines are used for showing the bonding electrons of the sigma bond between the Sulfur and Hydrogen atom.
SH2 lewis structure shape can be derived from the VSEPR theory (Valence shell electron pair repulsion theory).
This theory states that the molecule will be stable if there is minimum repulsion between the outer most orbit electrons. So the outer most orbit electrons arrange themselves accordingly.
This theory assumes that, the unshared electrons (lone pair) remains in control of the belonging atom with more space than the bonding electron cloud. The repulsion between lone pair- lone pair electron is greater than the repulsion between bond pair- bond pair electrons.
Hence if a central atom contains nonbonding electron cloud, the geometry of the molecule disturbed for the repulsion.
Hybridization of atomic orbital of the central atom Sulfur is sp3 in the molecule. For this the geometry of the molecule should be tetrahedral. But Sulfur atom has four unshared electrons.
For the repulsion between the two nonbonding electron pair cloud, the structure of the molecule becomes disturbed. To minimize the repulsion the shape of the molecule become “V” liked shape.
The formal charge of an atom is calculated assuming that all atoms of the molecule having the same electronegativity.
Formal charge of a atom in a molecule = (total number of outer shell electrons – nonbonding electrons – (1/2×bonding electrons))
From the Periodic table group numbers of the atoms, we know that outer most orbit electrons of Sulfur are six and that of Hydrogen is one. Sulfur atom has four unshared electrons whereas Hydrogen atom has no such type of electrons in the molecule.
Formal charge for the central atom Sulfur is = {6- 4- (1/2×4)} = 0.
Formal charge for the each Hydrogen atom is = {1- 0- (1/2×2)} = 0.
As the individual atoms in the molecule have zero formal charge, hence the formal charge of the molecule, SH2 is also Zero.
SH2 lewis structure lone pairs
In a molecule lone pairs are the electrons which don’t take part in the bonding formation with the other atoms. These only concentrate over the parent atom.
In Sh2 lewis structure, there total eight outer shell electrons participate. Among these electrons only four electrons make bond between the central atom Sulfur and the two Hydrogen atoms. Remaining four electrons are unshared electrons.
The four nonbonding electrons belong to the 3s and 3p orbitals of the Sulfur atom.
SH2 hybridization
In the Valence bon theory, concept of hybridization is very much important as it can describe the shape of molecule.
In the concept of Hybridization, atomic orbitals are mixing up.The new hybridized orbital differs with respect to the component orbitals in energy, shape. In the Hydrogen Sulfide molecule, we only consider the hybridization of the central atom, Sulfur. From this we can understand the shape of the molecule.
In the ground state of Sulfur atom, it has two unpaired electrons in 3p orbital. So it can form two bonds with another two atoms with these two unpaired electrons. Beside this it has two pairs of electrons, one is in 3s orbital and another one is in 3p orbital. These concentrate over the atom as lone pairs of electron.
After hybridization the overlap of the orbitals become greater in bond formation. Hence mixing up of orbitals occurs.
The new hybridized orbital is sp3 in nature. This sp3 hybridized orbital overlaps with the Hydrogen atomic orbital 1s to form molecule.
SH2 lewis structure resonance
When an atom contains nonbonding electrons, these can be able to delocalize into another atom of the molecule. In this way, resonance structure of a molecule form.
To delocalization of the electrons the accepter atom must have vacant orbital. In the SH2 molecule Hydrogen atom has no vacant orbital that it can accept electron from Sulfur atom. Hence no resonance structure can be formed.
SH2 lewis structure octet rule
The electronic stability of a molecule lewis configuration can be explained by this Octet rule.
All main group elements of the Periodic table like to have full filled outer orbitals with eight electrons. This preference is called the Octet rule. Only Hydrogen atom can have highest two electrons in the 1s orbital. This is because it has only ‘K’ orbit which contains only “s” orbital.
Sulfur has six electrons in the outer orbit 3s and 3p, as a ‘group 16’ element. It prefers two more electrons to be like nearest Noble gas Argon. Hydrogen atom has only one electron in the 1s orbit, so it accepts that electron from Sulfur atom.
In this way both cover eight electrons in the outer most orbits. For this the molecule becomes lower in energy. It gives the molecule stable structure like the noble gases have.
SH2 polar or nonpolar
Polarity is a physical property of a molecule if it has a net dipole moment. Bond dipole moment (µ) = separated charge (δ) × distance between charge(r).
In the Hydrogen Sulfide molecule, electro-negativity of Sulfur (S) is 2.58 and that of Hydrogen is 2.2 on the Pauling scale. As the atoms of the molecule have slightly difference in electro-negativity, an unequal charge separation occurs in the molecule. Also for the bent structure, sh2 becomes slightly polar in nature.
For the slight difference between electro-negativity, unequal charge separation occurs. This gives a direction of dipole moment. If these direction vectors can’t neutralize each other, a net dipole moment generates.
The geometry of the molecule should be tetrahedral. From VSEPR theory we know that lone pair- lone pair repulsion is greater than bond pair- bond pair repulsion. For the repulsion between nonbonding electron pairs cloud of the central atom Sulfur, the shape of the molecule becomes “V”- shaped.
For the distorted V- shape, the direction of dipole moments for electro-negativity, can’t cancel out each other. Hydrogen Sulfide become a slightly polar molecule.
Electron dot structure gives idea about the planer (2D) structure of a molecule. This article will discuss about SeCl4 lewis structure and the method of drawing it.
To draw SeCl4 lewis structure, the atomic symbols of atoms are written,the outer orbit electrons of the atoms are shown by dot symbols.From this we can predict many propeerties like hybridization, shape, polarity etc.
How to draw lewis structure for SECL4
SeCl4 Lewis structure gives idea about outer most orbit electrons of the atoms. These electrons are responsible for characteristic properties in the molecule.
To draw SeCl4 lewis structure, the atomic symbols of atoms are written, that is ‘Se’ for Selenium and ‘Cl’ for Chlorine The outer orbit electrons of an atom are shown by dot symbols around that particular atom of the Selenium tetrachloride molecule.
Selenium is a ‘group 16’ element and Chlorine is a ‘group 17’ element in the Periodic table.
Electronic configuration of Selenium: [Ar] 3d10 4s2 4p4. Electronic configuration of Chlorine: [Ne] 3s2 3p5. So outer most orbit electrons of Selenium atom are six and that of Chlorine atom are seven.
For four Chlorine atoms and one Selenium atom, the total number of the outer orbit electrons are {6 + (7×4)} =34. Hence 17 pairs of electrons participate to form a SeCl4 molecule.
Being the less electronegative atom, Selenium is the central atom in the molecule. Chlorine atoms are around the central atom. Four Chlorine atoms form sigma bonds (single bond) with Selenium atom. Eight electrons (four pairs of electrons) take part in bond formation.
Each Chlorine atom of the SeCl4 molecule has six unshared electrons. Central atom Selenium has one pair of unshared electron over it.
Straight lines are used for showing the bonding electrons of the sigma bond in the molecule.
SeCl4 lewis structure shape can be found out with the help of VSEPR theory (Valence shell electron pair repulsion theory).
This theory states that the outer most orbit electrons of the atoms are arranged in a way that there is a minimum repulsion between the electrons in the molecule.
This theory assumes that, the unshared electrons (lone pair) cover more space than the bonding electrons. The repulsion between lone pair- bond pair is greater than the repulsion between bond pair- bond pair. Hence if a central atom contains unshared electron pair, the geometry of the molecule disturbed.
Hybridization of central atom Selenium is sp3d in the molecule. For this the geometry of the molecule should be trigonal bipyramidal. But central atom has one unshared pair of electron. For repulsion the molecule has a distorted tetrahedral shape.
Shape of Secl4
SECL4 lewis structure formal charges
The electron dot structure which has ‘zero’ formal charge that is regarded as the stable structure of the molecule among all the possible electron dot structure.
Formal charge of a atom in a molecule = (total number of outer shell electrons – nonbonding electrons – (1/2×bonding electrons))
From the lewis structure of the molecule, we know that outer most orbit electrons of Selenium are six and that of Chlorine are seven. Selenium atom has two unshared electrons whereas each Chlorine atom has six unshared electrons.
Formal charge for the central atom Selenium is = {6- 2- (1/2×8)} = 0.
Formal charge for the each Chlorine atom is = {7- 6- (1/2×2)} = 0.
As the charge on the individual atoms in the molecule is zero, hence the formal charge of the molecule, SeCl4 is also Zero.
SECL4 lewis structure lone pairs
In a molecule lone pair contains such type of electrons which don’t take part in the bonding formation.
In SeCl4 lewis structure, there are 34 outer shell electrons that mean 17 pairs of electrons. Among these electrons only eight electrons make bond between the central atom Selenium and the four chlorine atoms. Remaining all are unshared electrons.
There are thirteen pairs of electrons that not participate in the molecule formation. Among these each Chlorine atom has three pair of that electrons and Selenium has one pair of unshared electrons or lone pair.
SECL4 hybridization
In the concept of hybridization, mixing of atomic orbitals take place. The component orbitals are comparative in energy.
The new hybridized orbital is different in energy with respect to the component orbitals. In the Selenium tetrachloride molecule, only consider the hybridization of the Selenium atom. This helps to determine the geometry of the molecule.
In the unexcited Selenium atom, it has two unpaired electrons in 4p orbital. Beside this it has two pair of electrons in the outer orbit, one is in 4s orbital and another one is in 4p orbital. So it can form two bond pair in this state.
But Selenium has ‘d’ orbital, where paired electrons from 4p orbital can sift and become unpaired one. Now the 4s orbital, three 4p orbital and one 4d orbital mixed up together. This results in the formation of sp3d hybridized orbital.
The hybridized orbital are same in energy. So the bonding overlap of the new orbital with the ligand orbitals becomes better than the unhybridized orbitals.
SECL4 lewis structure resonance
SeCl4 lewis structure may have many forms. The electron dot structures are made by delocalizing of the unshared electrons.
In Selenium tetrachloride molecule, both the Selenium and Chlorine atoms have pair of unshared electron. They can delocalize from the parent atom and form resonating structure. Among these lewis structures, which have the ‘zero’ formal charge that would be the real configuration.
Chlorine is more electronegative than the Selenium atom. So it can bear the negative charge easily. Pi (π) back bonding occurs i.e.4pπ (Se) – 3dπ (Cl) in the molecule.
It means that the unshared electron of Selenium delocalized to the vacant 3d orbital of the Chlorine atom. This results in the formation of the partial pi (π) bonding in the molecule.
As the nonbonding electrons of the Selenium atom involve in the back bonding the repulsion between the bonding electron pair and this unshared electron pair decreases.
SECL4 lewis structure octet rule
Octet rule relates with the electronic stability of the elements in the Periodic table.
All main group elements of the Periodic table like to have eight electrons in the last orbit. This tend to have full filled orbitals is named as Octet rule. Only Hydrogen atom can have highest two electrons in the orbit. This is because it has only ‘K’ orbit.
Selenium has six electrons in the outer orbit. It prefers two more electrons to be like nearest Noble gas Krypton. Chlorine atom has seven electrons in the outer orbit, so it accepts that electron from Selenium atom. In this way both cover eight electrons in the outer shell. This gives the molecule stable structure.
SECL4 polar or nonpolar
Polarity is a physical property of a molecule if the molecule has a net dipole moment generated by polar bonds.
In the Selenium tetrachloride molecule, electronegativity of Selenium (Se) is 2.55 and that of Chlorine is 3.16 on the Pauling scale. For this difference between the electronegativity of the atoms, an unequal charge separation occurs in the molecule. This results a net dipole moment e and SeCl4 becomes polar.
The capacity of strongly pulling the electron cloud of a covalent bond towards the atom is the measurement of electronegativity of that atom. The electronegativity gives a direction of dipole moment. If these direction vectors are not cancelled out each other, a net dipole moment generated.
In the Selenium tetrachloride molecule, Selenium atom has six outer most orbit electrons where Chlorine atom has seven outer shell electrons. SeCl4 molecule has total 34 outer most orbit electrons in the molecule. Among these eight electrons (4 pairs of electron) make bond in the molecule and Selenium has two unshared electrons (one pair of electron).
The geometry of the molecule should be trigonal bipyramidal. From VSEPR theory we know that lone pair- bond pair repulsion is greater than bond pair- bond pair repulsion. For the nonbonding electron pair of the central atom Selenium, the shape of the molecule becomes distorted tetrahedral.
For the distorted shape, the direction of dipole moments for electronegativity difference, can’t neutralized each other. Selenium tetrachloride become a polar molecule
Proteins are complex type of bio-molecules. Amino acids are the basic structural component of protein molecule. This article will discuss the Histidine structure.
Among the twenty amino acids that found in human body, there are some amino acids that can’t be synthesized. These are taken from diet and are called the essential amino acids. Histidine is one of them. Imidazole is present as side chain in Histidine structure.
The IUPAC name of Histidine is 2-amino-3-(1H-imidazol-5-yl)propanoic acid. Generally it is written as His.
In Histidine sttructure, there is a central Carbon atom. The Carbon atom is attached with amino group and carboxyl group and one Hydrogen atom. The central Carbon atom contains a side chain, which is called imidazole.
Histidine is an alpha (α) Amino acid as in the Histidine structure, both (-NH2) and (-COOH) groups are attached to the central Carbon atom.
The Hydrogen atom which is directly attached to the central Carbon atom of the alpha (α) amino acid; this is called the alpha (α) Hydrogen. There is a alpha (α) Hydrogen atom in Histidine structure.
Zwitter ion of Histidine structure
If a molecule has both positive and negative charge, it is called a zwitter ion.
Carboxyl (-COOH) is an acidic group. It transfers the Hydrogen atom. Nitrogen atom of amino group (-NH2) is basic in nature. So the Hydrogen atom is taken by the amino group. Hence a zwitter ion forms with both opposite charges.
The zwitter ion of Histidine structure has both positive and negative charges in the molecule. The opposite charges neutralized each other. But the net charge of the molecule depends on the pH of the environment.
pH dependence of zwitter ion
At pH lesser than 6, the side chain absorbs a Hydrogen atom. The ring of the side chain becomes positively charged. The charge density is equally spread between the two Nitrogen atoms of the ring.
Histidine structure of zwitterion
At pH greater than 6, one of the Nitrogen atoms of the ring lost its proton. The imidazole ring of the side chain of Histidine molecule remains aromatic in nature at any pH of environment.
This property of donation and acceptance of Hydrogen atom of the side chain of a Histidine molecule can help in many catalytic reactions.
Chemical nature of Histidine
An amino acid can be acidic, basic or neutral. It depends on the nature of the side chain of the amino acid. As the side chain part of the Histidine is basic in nature, hence Histidine is a basic amino acid.
Electronic property of Histidine
The Histidine molecule has charges in the molecule structure. So Histidine is a good conductor of electricity for the ionic structure in the solid phase.
Solubility of Histidine molecule
Histidine contains a imidazole group in the side chain. For this it is an example of polar amino acid. Hence it can soluble in water.
The basic imidazole group forms strong Hydrogen bonding between the surrounding molecules. For this Histidine is hydrophilic in nature.
But Histidine can’t soluble in solvents that are not polar, like Benzene. Because these solvents can’t be able to dissolve the polar imidazole group or ionic part of Histidine.
Moleculewith chiral Carbon
If four different groups are attached with a central Carbon atom; then the Carbon atom is called a chiral Carbon center.
For this the molecule becomes optically active in nature. It can rotate the plane of light (polarized).
These types of molecules contain two structure which are ‘D’ and ‘L’. These structures are mirror image like but not same in configuration.
Chiral nature of Histidine structure
Histidine has four different groups around the central Carbon atom which are amino group, carboxyl group, imidazole group and a Hydrogen atom. So this amino acid is optically active molecule.
It has two different structures like D- Histidine and L- Histidine.
D- Histidine structure
In the Fischer projection, D- Histidine molecule has the amino group (-NH2) to the right hand side of the central Carbon atom. The L- Histidine molecule has the amino group to the left hand side of the Carbon atom.
In both skeletal structures the alpha (α) Hydrogen atom is written in horizontal position.
L- Histidine structure
The D – Histidine molecule can rotate the plane of light which is polarized, to the clockwise direction (+). The L- Histidine molecule can rotate the plane of light which is polarized, to the anti- clockwise direction (-).
Amino acids in protein structure
Amino acids are the basic components which form the protein structure.
Protein molecules are a long chain of amino acids; adding one after another. The amino acids are added sequentially through Peptide bonds.
One molecule of water is removed in the Peptide bond formation reaction.
Peptide bond in Amino acid
The Peptide bond is formed between the carboxyl group of one Amino acid and amino group of another Amino acid next to it.
A free amino group is present in one side of the Peptide bond. This side is called N- terminus of the Peptide bond. A free carboxyl group is present on the other side. This end is called C- terminus of the Peptide bond.
Generally this N- terminus of the Peptide bond is written to the left side. The C- terminus of the Peptide bond is written to the right side in a long protein chain.
Lewis dot structure gives an idea about outer most orbit electrons of an atom. This article is discussing about the Acetone lewis structure and explanations.
Acetone Lewis structure is written with the atomic symbol of atoms in the molecule. The outer orbit electrons of a particular atom are shown by dot symbols around that particular atom.
These electrons may forms bond with the outer shell electrons of the atom next to it. Or some of these electrons don’t take part in bond formation, remains as nonbonding electrons.
Structural formula of Acetone molecule
Acetone is a molecule in Carbonyl family. It is a smallest ketone molecule with molecular formula C3H6O or (CH3)2CO. So an acetone molecule contains three Carbon atoms, six hydrogen atoms and one oxygen atom.
Acetone lewis structure drawing
To draw the lewis structure of Acetone, all the outer orbit electrons of these atoms are first calculated. Carbon is an element of ‘group 14’, Oxygen is an element of ‘group 16’ and Hydrogen is a ‘group 1’ element in Periodic table.
Outer orbit electron calculation
Electronic configuration of a Carbon atom: 1s2 2s2 2p2. Electronic configuration of an Oxygen atom: 1s2 2s2 2p4. Electronic configuration of a Hydrogen atom: 1s1.
Hence the number of outer most shell electron in a Carbon atom is four. That of an Oxygen atom is six and for a Hydrogen atom is one.
In the Acetone molecule the total outer shell electrons for three Carbon atoms are (4×3) = 12. For six Hydrogen atoms these electron number will be (1×6) = 6. For that one Oxygen atom the total outer most shell electron number will be (6×1) = 6.
Thus in a Acetone molecule the number of total electrons in the outer orbit of the atoms are 24.
In a bond forming between two atoms next to each other, there two electrons (a pair of electron) are involved.
We can find how many pairs of electrons participate in the bonding in Acetone molecule by dividing the number 24 by 2 and the number will be 12. As there are 24 outer orbit electrons in an Acetone molecule.
Total electron pairs which participate in molecule formation= total outer shell electrons in the molecule ÷ 2.
Arrangement of atoms in Acetone lewis structure
In Acetone lewis structure, the arrangement of atoms occurs in a way that generally the atom with less electronegative character will be the central atom in a molecule.
Here Hydrogen is the less electronegative atom. To be the central atom, at least it has to connect with two other atoms. Hydrogen has only one electron, so it can’t be the central atom.
Carbon becomes the central atom in the Acetone molecule. Hydrogen and Oxygen atoms are placed around the Carbon atoms. The bonding pair electrons are shown with straight lines between two atoms.
For now in the lewis structure, total eighteen electrons (nine pairs of electrons) are involved in bond formation.
As Hydrogen is a ‘group 1’ element it has no vacant orbital for the nonbonding electrons. Three unshared pairs of electrons are written over the Oxygen atom of the molecule.
Formal charge calculation
Now the formal charges of the atoms of Acetone have to calculate to properly distribute the electrons among the atoms.
Formal charge of a atom in a molecule = (outer shell electrons – nonbonding electrons – (1/2×bonding electrons))
The formal charge of the Carbon atom, attached with Hydrogen atoms = (4 – 0 – (1/2×8)) = 0.
The formal charge for the Carbon atom, attached with the Oxygen atom = (4 – 0 – (1/2×6)) = +1.
The formal charge of the Hydrogen atom = (1- 0 – (1/2×2)) = 0.
The formal charge of the Oxygen atom = (6 – 6 – (1/2×2)) = -1.
Stability consideration with formal charge
The structure is not a stable one as both the Oxygen and the central Carbon atom has formal charges.
To obtain a stable Acetone molecule structure the charges have to neutralize. This can be made by converting the unshared electrons into bond formation between the Oxygen atom and the central Carbon atom.
In the Acetone lewis structure there forms a pi bond (double bond) between the central Carbon atom and the Oxygen atom. Beside this the molecule has nine sigma bonds ( single bond).
The Oxygen atom of Acetone molecule has four unshared electrons. These electrons are written as pair of dot sign over the Oxygen atom.
Now if we count the outer shell electrons of each atom in the Acetone lewis structure, we found that every outer orbit of the atoms is full filled with electrons. This is the main condition for a stable configuration according to the Octet rule.
The amount of trans fatty acid, found naturally is very small. The processed foods contain a large amount of trans fatty acid. In the article we see trans fatty acid structure and other facts about it.
Trans fatty acids are one type of unsaturated fatty acids with Carbon – Carbon double bond. The structure is a long hydrocarbon chain. In the trans fatty acid structure there is a Carboxylic group (-COOH) at the end of the hydrocarbon chain.
The fatty acids that are not saturated, are classified into two groups. In one type of the fatty acids, there one double bond present, these are called monounsaturated fatty acid. In another type of fatty acids, there present more than one double bond in the hydrocarbon chain. These are called polyunsaturated fatty acids.
In the trans fatty acid structure the word ‘trans’ identifies the configuration of the hydrocarbon chain. It means the Hydrogen atoms on the double bond are in opposite direction with respect to each other. For the pi bond present in the hydrocarbon chain, the structure is in locked position.
Trans fatty acids are isomer of cis fatty acids. The trans fatty acids are less common with respect to the cis fatty acids in nature.
In the fatty acid chain, the carbon atoms of the carbon – carbon double are sp2 hybridized. So they remain in same plane. For the trans bond present in the fatty acid chain; the trans fatty acid has a straight chain structure. The chain can’t bend much.
Most of the fatty acids have even number of Carbon atoms in the hydrocarbon chain. Some of the fatty acids have odd number of Carbon atoms in the fatty acid chain. These are called odd chained fatty acids.
Most of the fatty acids have no branch in the hydrocarbon chain which we find naturally. In the trans fatty acid structure, hydrocarbon chain has a carboxyl group (-COOH) at one end of the chain. In another end of the chain there is a methyl group (-CH3).
In general for numbering of the hydrocarbon chain of the trans fatty acid; the Carbon atom next to the Carboxyl group is pointed as alpha (α) Carbon. So it is the second carbon atom of the chain. Next to the alpha Carbon is called as beta Carbon (β). The last Carbon atom is said to be the omega (Ѡ) Carbon.
The number of the position of the double bond of the trans fatty acid chain is given from which side the carboxyl group is closest. In a fatty acid chain there are 16 Carbon atoms and the double bond is between the 12th carbon (C-12) atom and the 13th carbon atom (C-13). In this case the numbering of the double bond is said to be at C-12.
The sign ∆x,y is used for showing the position of the double bond at the carbon atoms x and y in the hydrocarbon chain. For example ∆5,8 means that the hydrocarbon chain of the fatty acid contains pi bond between the carbon atoms 5 and 6, and between 8 and 9.
Trans fatty acid structure
For the straight chain structure of the trans fatty acids, they can form packed structure easily in solid state. This indicates that the trans fatty acids easily convert them into semi-solid form from the oil. Because of this the melting point of the fatty acid is higher.
Trans fatty acid structure are produced from cis fatty acids through isomerization process in hydrogenation. Naturally trans fatty acids occurs in ruminant meat and milk in a small amount. Elaidic acid is a trans fatty acid. It is found in vegetable oil.
Besides these during the heating and frying of oil at high temperature results in the formation of trans fatty acids.
If one take high amount of trans fatty acid containing food, it increases the cholesterol level in the blood which is harmful for our health. It increases the heart problem possibility. In our present day, a huge amount of world population is suffering from obesity problem. Taking foods containing trans fatty acid type unsaturated fats is a reason for it.
The scientists found twenty Amino acids in a human body which form proteins. Serine is one among these amino acids. In this article we see the Serine amino acid structure and facts about it.
Among the twenty Amino acids; some amino acid can be synthesized in human body, they are called non- essential amino acids. Serine is a non essential amino acid. The IUPAC name of Serine is 2-amino-3-hydroxypropanoic acid. It is a neutral amino acid with amino and carboxyl groupin Serine amino acid structure.
Amino acids are carboxylic acids. These acids have commonly two functional groups. One functional group is amino group and another functional group is Carboxyl group. Beside these the amino acid structure contains a side chain. This is written as ‘R’ in general in the structure.
Serine also has the amino (-NH2) group and the Carboxyl (-COOH) group. As a side chain Serine has a hydroxymethyl (-CH2OH) group. It is connected to central Carbon atom. There also an alpha (α) Hydrogen atom is present in the amino acid.
Amino acids contains both (-NH2) and (-COOH) groups. (-COOH) is an acidic group and tends to donate the Hydrogen atom. This Hydrogen atom is accepted by the amino group present in the molecule as it has a basic nature. Hence Serine exists as a zwitter ion with both opposite charges.
As a zwitter ion Serine has both positive and negative charges in the molecule. Both the opposite charges neutralized each other. As a whole the molecule has no charge. It is a neutral molecule.
The ionic form of the zwitter ion of the amino acid depends on the pHof the solution. At a strong acidic pH (pH<2), the ion accepts protons from solution and cationic forms are observed. In a strong basic pH (pH>11), the ion donates proton and anionic dorms are observed.
The amino acids have both charges present in the molecule. So serine is a good conductor of electricity for the zwitter ion structure in the solid phase.
Serine contains a hydroxyl group in the side chain. For this it is a polar amino acid. It can soluble in water as a result of the polarity. The Hydroxyl group forms strong Hydrogen bonding between the surrounding molecules. This makes the molecule hydrophilic in nature that means it produces a tendency to mix with water.
But Serine could not soluble in solvents that are not polar, like Benzene, Ether etc. Because these non- polar solvents could not able to dissolve the polar hydroxymethyl group or ionic part of Serine.
If a molecule has four different groups coordinate with a central Carbon atom; then the Carbon atom is called a chiral Carbon center. This means that the molecule is optically active in nature. It has ‘D’ and ‘L’ sttructures. These structures are mirror image to each other but not same.
Serine has four different groups around the central Carbon which are amino group, carboxyl group, hydroxymethyl group and a Hydrogen atom. So the amino acid is optically active molecule. It has two different structures like D- Serine and L- Serine.
For convention; the D- Serine molecule has the amino group (-NH2) to the right hand side of the central Carbon atom. The L- Serine molecule has the amino group to the left hand side of the central Carbon atom.
Amino acids are the basic unit in the formation of protein structure. Protein molecules are formed by joining the Amino acids one after another. The bond formed between two Amino acids is called the Peptide bond. In the bond formation reaction one molecule of water is removed.
This joining of the Amino acids occurs systematically. The bond is formed between the carboxyl group of one Amino acid and amino group of another Amino acid next to it. In one side of the Peptide bond a free amino group is present, it is called N- terminus of the bond. On the other side a free carboxyl group is present, this end is called C- terminus of the bond.
For convention, the N- terminus of a Peptide bond is written to the left side and the C- terminus of the bond is written to the right side.
Lewis dot structure gives information about outermost shell electrons of an atom. This article is discussing about the Rubidium lewis dot structure involving in bonding with different elements.
Rubidium lewis dot structure is written by Atomic symbol of the atom ‘Rb’. The outer orbit electrons are written around ‘Rb’ as dot sign. Rubidium is a ‘group 1’ element with one outer most shell electron. It always tries to donate that electron to an acceptor atom. This gives the Rubidium atom stable electronic structure like nearest Inert gas.
Rubidium is a ‘Group 1’ element in periodic table with total 37 electrons. It has one electron in outer most orbital 5s.
Octet rule informs that every element covers its last orbit with highest possible number of electrons. This makes the element energetically more stable. So Rubidium transfers the outer shell electron to obtain the stability like nearest Noble gas. Thus it becomes a positive ion.
The symbol of Rubidium ‘Rb’ is written. As it donates the outer shell (5s) electron, there will be no dot sign around the atomic symbol. The atomic symbol is written into a third bracket ([ ]). The positive charge developed on the atom for donating the 5s electron; is written outside the bracket at upper right side.
Rubidium is in group 1 in periodic table. So it has one outer most shell electron in 5s orbital ([Kr] 5s1). Sulfur is a ‘group 16’ element. Its electronic configuration: [Ne] 3s2 3p4.
Rubidium atom donates the outer orbital 5s electron. Hence it becomes a ion, carrying positive charge. For this it develop an energetically stable configuration like nearest inert gas. Sulfur atom takes the electron in vacant 2p orbital and form Sulfide ion.
Sulfur atom requires two electrons to fill up its outer 2p orbital. It adds with two positively charged Rubidium ions and produce Rb2S molecule.
Electrons that form sigma bonds between Rubidium and Sulfur are shown as straight lines in the electron dot structure of Rubidium sulfide.
Fluorine is a ‘group 17’ element. It has seven electrons in last shell which are in 2s and 2p orbital. Rubidium has one outer orbital electron which is in 5s; as a ‘group 1’ element.
Fluorine atom requires one electron to make energetically stable outer orbit structure. Rubidium transfers its one outer shell (5s) electron to electronegative Fluorine atom.
These two oppositely charged Rubidium and fluoride ion produce a molecule with sigma bond formation.
In the electron dot structure of the molecule Rubidium atom has no any unshared electrons in outer orbital. Fluorine atom has six unshared electrons in the outer shell.

The first ionization energy of krypton is high at 1350.8 kJ/mol, signifying its low reactivity. Krypton’s full valence shell is a key factor in its limited chemical reactivity, typically not forming compounds under normal conditions, though a few compounds like KrF2 are known under specific conditions.

Krypton valence electron configuration
Electrons are specifically organized in different orbits; this arrangement is called the electron configuration of an atom.
Krypton has 36 electrons. These electrons are arranged into a particular manner around nucleus. Here we discuss the configuration of electrons in both orbit and orbital.
Scientist Niels Bohr gave the concept of orbit of an atom. The electrons are moving around the nucleus through specific shells which are called orbit. 1st orbit name is ‘K’, 2nd orbit name is ‘L’, 3rd orbit name is ‘M’, 4th orbit name is ‘N’ and so on. The no of electrons in each orbit is 2n^2 (n=1, 2, 3,….).
In a Krypton atom 1st orbit has two electrons (2*1^2), 2nd orbit has eight electrons (2*2^2), 3rd orbit has 18 electrons (2*3^2), 4th orbit has remaining eight electrons. The electronic configuration will be 2, 8, 18, 8.
These shells (orbit) are divided into sub-shells (orbital). The name of the sub energy levels are ‘s’, ‘p’, ‘d’, ‘f’. Physicist Aufbau first show the configuration of electrons in the orbital. The lower energy orbital is 1st covered with electrons.
In Krypton the 1st two electrons fill the 1s orbital. ‘s’ orbital can have maximum two electrons. Next two electrons fill the 2s orbital. Next energy sub-shell is 2p, it contain total six electrons. Like this 3s and 3p orbitals fill up.
Next 4s sub-shell fills with two electrons. After this 3d orbital fill with ten electrons and remaining six electrons fill the 4p sub-shell. Hence the outer shell electrons are in 4s and 4p orbitals. The valence electronic configuration of Krypton lewis dot structure will be: [Ar] 4s2 4p6.

In the study of chemical bonding and molecular structure, Lewis dot structures play a crucial role in visualizing the arrangement of electrons in a molecule. Specifically, when it comes to nitrogen (N) atoms, understanding the Lewis dot structure provides valuable insights into its electron configuration and bonding behavior.
In the Lewis Dot Structure for NH3, How Many Dots Are on the Nitrogen?

Therefore, the Lewis dot structure for NH3 will have a total of eight dots around the nitrogen atom, representing its five valence electrons.
Nitrogen Oxide Lewis Dot Structure
Nitrogen oxides are a group of chemical compounds that contain nitrogen and oxygen atoms. One example is nitrogen monoxide, also known as nitric oxide (NO). To determine the Lewis dot structure for nitrogen oxide, we need to consider the valence electrons of both nitrogen and oxygen.

To achieve a stable electron configuration, nitrogen can share one electron with oxygen, forming a covalent bond. This shared electron pair is represented by a line between the nitrogen and oxygen atoms in the Lewis dot structure.
In addition to the shared electron pair, the remaining valence electrons of nitrogen and oxygen are represented as dots around their respective symbols. Nitrogen will have three lone pairs of electrons, while oxygen will have two lone pairs. These lone pairs and the shared electron pair contribute to the overall molecular geometry and chemical properties of nitrogen oxide.

1. What is the nitrogen electron dot structure?
The nitrogen electron dot structure, also known as Lewis dot structure, represents the valence electrons of a nitrogen atom. Nitrogen has five valence electrons, so its Lewis dot structure is represented as ‘N’ with five dots around it.
2. How is the nitrogen monoxide Lewis dot structure depicted?
The nitrogen monoxideLewis dot structure is depicted by showing the covalent bonding between nitrogen and oxygen. Nitrogen contributes five valence electrons and oxygen contributes six, making a total of eleven. They share a pair of electrons to form a covalent bond, and the remaining electrons are shown as lone pairs.
3. How many unpaired electrons are there in nitrogen’s Lewis dot structure?
In nitrogen’s Lewis dot structure, there are three unpaired electrons. This is because nitrogen has five valence electrons and in its ground state, two of these electrons are paired up in one orbital, leaving the other three unpaired in three separate orbitals.
4. In the Lewis dot structure for NH3, how many dots are on the nitrogen?
In the Lewis dot structure for NH3 (ammonia), there are eight dots on the nitrogen. This includes the six electrons involved in bonding with the three hydrogen atoms and two lone pair electrons.
5. Can you explain the nitrogen ion Lewis dot structure?
The nitrogen ion Lewis dot structure shows the electron configuration when nitrogen gains or loses electrons to achieve a full valence shell. When nitrogen gains three electrons to become N3-, it has eight electrons in its valence shell, represented by eight dots around ‘N’ in the Lewis dot structure.
6. What does the nitrogen dioxide Lewis dot structure look like?
The nitrogen dioxide Lewis dot structure consists of nitrogen in the center bonded to two oxygen atoms. Nitrogen shares two electrons with each oxygen atom to form two covalent bonds. The remaining electrons on the oxygen atoms are represented as lone pairs.
7. How is the calcium nitrogen Lewis dot structure represented?
The calcium nitrogen Lewis dot structure represents the ionic bonding between calcium and nitrogen. Calcium loses two electrons to achieve a stable electron configuration and these two electrons are gained by nitrogen. This results in the formation of Ca2+ and N2- ions.
8. Can you describe the nitrogen trichloride Lewis dot structure?
The nitrogen trichloride Lewis dot structure shows nitrogen in the center bonded to three chlorine atoms. Each chlorine atom shares one electron with nitrogen to form three covalent bonds. The remaining electrons on the chlorine atoms are shown as lone pairs.
9. How many electrons would a nitrogen Lewis dot structure have?
A nitrogen Lewis dot structure would have five electrons, as nitrogen has five valence electrons. These electrons are represented as dots around the chemical symbol ‘N’ in the Lewis dot structure.
10. What is the nitrogen gas Lewis dot structure?
The nitrogen gasLewis dot structure shows a nitrogen molecule (N2) where each nitrogen atom shares three electrons with the other, forming a triple covalent bond. The remaining electrons are shown as lone pairs.
