Question

Assertion (A) Bond cleavage in haloarene is difficult than haloalkane.
Reason (R) Phenyl carbocation is more stable.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$
• C. $A$ is correct; $R$ is incorrect
• D. $R$ is correct; $A$ is incorrect

Answer 1

Answer: (C)

Bond cleavage in haloarene is difficult than haloalkane due to partial double bond. Character in $C - Cl$ bond because of resonance, so it is less reactive towards nucleophilic substitution reaction. Phenyl carbocation is very unstable.
