C-Cl bond is stronger than C-I bond , ...

C-Cl bond is stronger than C-I bond , because

A

C-Cl bond is more ionic than C-I

B

C-Cl bond is polar covalent bond

C

C-Cl bond is more covalent than C-I

D

C-Cl bond length is longer than C-I

Text Solution

Verified by Experts

The correct Answer is:
A
(i) C-Cl bond length is shorter than C-I bond length hence stronger because chlorine atom is smaller in size as compared to iodine atom.
(ii) C-Cl bond is more ionic than C-I bond because of greater difference in electronegativities of C and Cl as compared to that of carbon and iodine.
(iii) More ionic character of bond , more will be its strength .
`:.C-Cl` bond is stronger than C-I bond because C-Cl bond is more ionic than C-I .
