Naoch3 Lewis Structure& Characteristics: 19 Complete Facts


Mgh2 structure is widely used as reagent in industrial purpose. Let us talk about important characteristics of sodium methoxide (naoch3) structure in details below.

Naoch3 lewis structure appears as white amorphous powder. This molecule has vigorous water affection, soluble in methanol, ethanol. But it is insoluble in hydrocarbon like organic solvent. It is stored under inert atmosphere.

Naoch3 is used as catalyst to process of edible fats. It reacts with water and form methanol which is volatile in nature and excess absorption is damaging for health. Let us focus on resonance, formal charge, valence electron and many more questions on naoch3 lewis structure with explanation.

How to draw naoch3 lewis structure?

Naoch3 lewis structure can be drawn by atomic symbol of participated elements with outer orbit electrons. Let us check following steps to draw naoch3 lewis structure.

Step 1: sum up total valence electrons

Total valence electron participated in naoch3 lewis structure is, [1+ 6+ 4+ (3×1)] = 14. Because in naoch3, sodium and hydrogen are from group 1, oxygen is group 16 element and carbon is group 14 element in the Periodic table. 

Step 2: arrange electrons around atomic symbol

Naoch3 is ionic compound made by methoxide and sodium ion. Here electron is fully transferred from sodium to vacant orbital of oxygen. In methoxide group 4 covalent bonds are present between carbon- hydrogen and carbon- oxygen. These bonds are formed by sharing electron cloud equally.

Step 3: checking the octet rule for each atom

In naoch3, sodium is completed the octet structure of outer shell by giving 3s electron to oxygen. Oxygen fills octet arrangement by accepting this and also by sharing electron with carbon atom. Carbon and hydrogen atoms share electrons to satisfy the octet and duplet rule respectively.

Naoch3 lewis structure resonance

In covalent type of molecules, resonance structures are produced by spreading of electron cloud to neighbor atom orbital. Let us see if naoch3 has such structure in below.

Naoch3 lewis structure can’t make such resonance structure.  The rigid structure of naoch3 is formed by fully electron transformation from sodium atom. For this ionic bond, structure is stabilized by electrostatic force. Electron cloud sharing can’t occur to produce canonical structure.

Naoch3 lewis structure shape

Shape of a covalent molecule is formed from its real geometry. Non bonding electron pairs distorted geometry. Let us figure out if naoch3 lewis structure has shape.

Naoch3 lewis structure shape can’t be identified for its ionic nature. According to VSEPR theory, molecular shape is found on the basis of the hybridization of molecular orbital. Naoch3 is formed without orbital intermixing so shape of the structure can’t be stated.

Naoch3 lewis structure formal charge

Formal charge is theoretically calculated to find electronically stabilized structure of covalent compound. Let us find if formal charge can be calculated for naoch3.

Naoch3 lewis structure formal charge can’t be calculated. Because it is an ionic compound. Formal charge is measured with bonding and non bonding electrons by the formula,[ valence electrons- lone pairs-(bonding electrons/2)] in covalent molecule.

Naoch3 lewis structure angle

Structure angle is measured to understand geometry of a covalent compound. Let us discuss lewis structure angle of naoch3.

Naoch3 lewis structure angle is not measured as it is ionic compound. In this compound, oppositely charged ions are bound by strong electrostatic force in rigid order. Lewis Structure angle is distance between overlapping orbitals. But naoch3 structure bond is formed by fully electron transfer.

Naoch3 lewis structure octet rule

Octet rule is calculated to find energetically stabilized electronic conformation. Let us explore if naoch3 lewis structure obeys the rule.

Naoch3 lewis structure full fills the octet rule. The outer 3s electron of sodium is fully transferred to vacant 2p orbital of oxygen atom. Here sodium satisfies stabilized octet structure like nearest noble gas ‘Ne’. Methoxide also complete octet structure with required valence electrons.

Naoch3 lewis structure lone pairs

Lone pairs of electrons are nonbonding electrons remains to the parent atom in molecule. Let us find if naoch3 contains such type of electrons.

Naoch3 lewis structure has two lone pair over oxygen atom. In spite of ionic nature naoch3 has covalent bonds in methoxide group. Oxygen shares one electron with carbon atom and accepts one electron from sodium atom. Other four electrons don’t participate in bonding known as lone pair.

Naoch3 valence electrons

Last orbit electrons are referred as valence electrons in a molecule. Because they can participate in bonding. Let us learn about valence electrons of naoch3.

Naoch3 molecule contains fourteen valence electrons. These can be calculated as sodium atom has one 3s electron, oxygen has six 2nd orbit electrons and carbon has four valence electrons. Each of hydrogen contains one electron in their 1s orbital.

Naoch3 hybridization

In chemistry hybridization produces new electronic orbital state where last shell orbitals can intermix. Let us understand if this is possible for naoch3 molecule.

In naoch3 molecule hybridization of orbitals can’t be seen. In hybridization new hybrid orbital produces from intermixing of different energy and shape orbitals. But in naoch3 lewis structure 3s electron of sodium is completely transferred. So here is no necessity for forming of hybrid orbital.

Is naoch3 a solid?

Solid is one of the physical states of matter. Let us see if we can find naoch3 in solid state.

Naoch3 is a solid matter. It appears as white amorphous powder. There is lack of sharp order in arrangement of the constituents in solid form. For this it becomes amorphous instate of crystalline powder.

Why naoch3 is solid?

Naoch3 can be found as solid because the elements are systematically organized in polymeric structure. There four oxygen centers are surrounded to a Na (+) center. Strong electrostatic force is acting between the elements to give the rigid solid structure.

How naoch3 is solid?

Naoch3 is solid state matter which can be understood by its melting point. For highly ordered lattice structure the decomposition of solid matters take much energy. This is the reason for high melting point of naoch3 that is 127̊ C.

Is naoch3 soluble in water?

Solubility is measured at a particular pressure and temperature how much solute is solvated to form saturated solution. Let us find if naoch3 is soluble in water.

Naoch3 is soluble in water and also decomposes in it. Sodium methoxide forms methanol (CH3OH) and sodium hydroxide (NaOH) in reaction with water.

Why and how naoch3 is soluble in water?

Naoch3 is soluble in water as it can form hydrogen bond with water molecules. The highly negative oxygen of naoch3 forms intermolecular bond with water molecule in aqueous medium. Naoch3 can also absorb water molecules from environment and hold them in lattice structure.  

Is naoch3 molecular?

Molecular compounds form with specific number of atoms. Let us explain why naoch3 is a molecular compound.

Naoch3 is a molecular compound with specific molecular formula. Each of sodium methoxide molecules contains one sodium and oxygen atom. There is also a methyl group made by carbon and hydrogen atoms.

Why and how naoch3 is molecular?

Naoch3 is hexa- atomic molecular compound as made of six atoms. The constituent ions are balanced their charge and form an ionic bond. The bond is between methoxide and sodium ion.

Is naoch3 polar or nonpolar?

Electro negativity difference greater than 0.5, creates charge separation in chemical bonds. Let us figure out if naoch3 has such partial charge in bonds.

Naoch3 is polar molecule. This is because of unequal charge separation in chemical bond between oxygen and sodium atom. Oxygen carries partial negative charge (δ-) and sodium carries partial positive charge (δ+).

Why and how naoch3 is polar?

Polarity is generated in specific molecular geometry where dipole can’t be cancelled out. Let us talk about the facts which causes naoch3 polar molecule.

Naoch3 is polar in nature in spite of having ionic bonding. Naoch3 also has covalent bond between oxygen and carbon. For more electron cloud attracting capacity, oxygen carries partial negative charge. Charge separation arises between oxygen and Na, causes the polarity.

Is naoch3 an acid or base?

In aqueous solution, producing hydroxide ion (OH-) or hydrogen ion (H+) ion decides basic or acidic nature. Let us find out if naoch3 is base or not.

Naoch3 is a strong base because it has greater affinity towards hydrogen ions (h+) or hydronium ions (H3O+). In protic medium it take hydrogen ions and forms methanol and sodium ions.

Why naoch3 is base?

Basicity can be known by pKa value of the conjugate acid of a compound. With higher pKa value the basicity increases. Let us explore the basic nature of naoch3.

Naoch3 is basic as having 15.5 pKa value.  Its conjugate acid can donate electrons to proton. This capacity is measured by pKa value. It is a monoprotic base as can form bond with one hydrogen ion.

How naoch3 is base?

Naoch3 is basic and this is increases by the inductive effect. The conjugate acid of naoch3 is stabilized by the positive inductive effect of the methyl group. This effect also increases the electron donation capability and increases the pKa value.

Is naoch3 an electrolyte?

Electrolytes are the compound those can transfer electricity throughout a solvent. Let us figure it out if naoch3 is an electrolyte.

Naoch3 can be an electrolyte molecule in methanol solution. Dilute solution of naoch3 is used in electrolyte cell. Then if electricity is applied flow of electricity can be measured.

Why and how naoch3 is an electrolyte?

Naoch3 dilute solution can be used as electrolyte. Because in solution, naoch3 dissociates in sodium ion (Na+) and methoxide ion. When electricity is connected the sodium ions and hydroxide ions (from methanol) carry the charge.

Is naoch3 a salt?

Salts are such chemical compounds which contain both anionic and cationic part. Let us check if naoch3 is a salt.

Naoch3 is a salt as it formed by two oppositely charged entities. Sodium is positively charged particle (cation) and methoxide is negatively charged particle (anion). These charges cancel out each other and maintained neutrality in molecule.

Why and how naoch3 is a salt?

Naoch3 is salt. Because salt can decompose through the ionic bond in dilute solvent in its components. Naoch3 also decomposes can carry charge in the electronic cell. But in solid form it is neutral.

Is naoch3 ionic or covalent?

In a molecule, bonding nature is dependent on electron cloud distribution between atoms. Let us discuss if naoch3 is covalent or ionic.

Naoch3 is ionic not covalent. That is because electron cloud is fully transferred between the sodium ion and methoxide ion. In covalent type of bonding, electrons are shared to satisfy the octet rule, not fully transferred.

Why and how naoch3 is ionic?

Outer orbit electronic configuration of element can show the nature of transferring of the electron cloud. Let us find this arrangement in case of naoch3.

Naoch3 is ionic as contains ionic bond. Being group 1 element sodium has one 3s orbital electron as valence electron. This is fully transferred to the vacant 2p orbital of oxygen. Thus both have filled stabilized orbital and resulting ionic bond.

Beside this ionic bond the compound also has covalent bonds in the methoxide group. But the ionic nature is developed by the ionic bond between the two main components.

Is naoch3 protic or aprotic?

Protic or aprotic nature depends on attachment of a hydrogen atom directly with any highly electro negative atom in molecule. Let us discuss if naoch3 is protic or not.

Naoch3 is aprotic in nature. Because in naoch3, no hydrogen atom is directly attached to the electronegative oxygen atom. All the three hydrogen atoms are bonded to the carbon atom. Here is no possibility to transfer hydrogen ions.

Why and how naoch3 is aprotic?

Aprotic solvents are unable to free partially charged hydrogen atom in solution. Let us analyze the facts behind this nature of naoch3.

Naoch3 is aprotic in dilute solution as it only can release sodium ions and methoxide ions. The hydrogen atoms in the methoxide group are bonded to carbon atom. There is low charge separation in the covalent bonds, so the hydrogen atoms can’t be released.

Is naoch3 a strong or weak nucleophile?

Nucleophile tends to attack to the nucleus as it is positively charged. Let us see if naoch3 is a strong or weak nucleophile.

Naoch3 is a moderately strong nucleophile in protic solvents like water or methanol. In spite of being a strong base naoch3 can’t become strong nucleophile. This is because the reaction path of the nucleophile.

Why naoch3 is moderate nucleophile?

In nucleophilic substitution reaction, electron rich nucleophiles replaces a functional group of an electron deficient molecule. Let us explore this for naoch3.

Naoch3 is moderate nucleophile. Because methoxide faces steric effect during formation of the transition state molecule. The steric effect hinders the reaction rate so naoch3 can’t be a strong nucleophile.

How naoch3 is moderate nucleophile?

Naoch3 is moderate nucleophile in protic solvents for the hydrogen bond formation. The methoxide group accepts hydrogen ion in solvents. Because of this it is no more capable to attack to the electrophiles sufficiently.

Conclusion:

Naoch3 molecule has one ionic bond along with four covalent bonds. The presence of these two type of bondings controls the properties of the chemical compound.
