Question

haloalkane are much less reactive than haloalkane towards nucleophilic substitution reaction
why​

Answer 1

Haloarenes are very much less reactive than haloalkanes towards nucleophilic substitution reactions. The lone pair of halogen atom is delocalized in the phenyl ring and development of partial double bond character in C—X bond,making it more strong. But no such resonance possible in case of saturated haloalkane.
