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 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 electrogativities of carbon (C) and Chlorine (Cl) as compared to that of carbon (C), and iodine (l).
(iii) More the ionic character of bond, more will be its strength.
`thereforeC-Cl` bond is stronger than `C-CI` bond because
`C-Cl` bond is more ionic than `C-I` bond.
