Question

$C-Cl$ 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 $C-I$

Answer 1

Answer: (A)

$C$ - $Cl$ bond is more ionic than $C-I$ bond because of the greater difference in electronegativities of $C$ and $Cl$ as compared to that of carbon and iodine. Therefore, $C-Cl$ bond is stronger than $C-I$ bond.
