Aryl halides are less reactive towards nucleophilic substitution because

Answer»

LESS stable carbonium ion
Due to large` C-CI` bond energy
INDUCTIVE effect
Resonance stabilization and `sp^(2)`-hybridisation of `C` ATTACHED to halide .

SOLUTION :Resonance stablization and the hybridisation of `C` attached to halides cis `p^(2)` .
