Haloarenes are less reactive than haloalkanes, why?

Answer»

SOLUTION :This is due to the following reasons:
(i) Haloarene involves resonance. eg. CONSIDER chloro berizene.
It has 5 resonating STRUCTURES.

Haloalkane has only one STRUCTURE eg. `CH_(3)-Cl`.
`:.` Haloarenes are more stable.
(ii) `"In Haloarene" = overset(sp^(2))overset(|)C-X` bond is lens polar than in haloalkanes.
(iii) In haloarenebond length is less than in haloalkanes
