Question

Define polar and nonpolar covalent bond give to property distance between the two bonds

Answer 1

Hello Dear.


Polar Covalent Bond →

The bond which is made between two atoms  which also combines in such a way that the shared pair of electron shift toward largest electronegative element is known as polar covalent bond.

Note ≈ The greater the difference in electronegativity the more the bond is polar. 

Examples ⇆ HCL , H₂O , HBr 


Non- Polar Covalent Bond→

Nonpolar covalent bond is the chemical bond b/w Two atoms that share electron equally or it is form between two very equal electron .

Examples ⇆ H₂ , Cl₂ , Cl-Br 

___________________


Property difference b/w Two bonds→

i) - In polar covalent bond electron are not equally shared While in non-polar covalent bond electron are equally shared.

ii)- Polar molecule formed through dipole- dipole intermolecular forces. Non polar interact through induced dipole forces. 

iii) Aqueous solution of Polar covalent bond acts as electrolytes.

Answer 2

Polar covalent bonding is the chemical bond where a pair of electrons are unequally shared between two atoms in which one has strong pull than other,instead say puller. When in solution form,it behaves like electrolytes and has dipole dipole intermolecular forces.eg-water, ammonia,sulphur dioxide

          And non polar bonding is distributed more equally as they dont have electrical poles.It does not act as electrolytes and has induced dipole forces between them. eg-helium,hydrogen,nitrogen,methane,etc.
