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

 834  139 Haloalkanes and Haloarenes Report Error

Solution:

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