Question

why haloarenes are less reactive than haloalkanes explain

Answer 1

Haloarenes are less reactive than haloalkanes towards nucleophilic substitution. ... Haloarenes are very much less reactive than haloalkanestowards nucleophilic substitution reactions.

Answer 2

Haloarenes are much less reactive than haloalkanes towards nucleophilic substitution reactions due to the following reasons: Inhaloarenes, the benzene ring undergoes resonance and as a result, the C−X bond acquires a partial double bond character. Therefore, it becomes difficult to break the C−X bond.
