Question

Chlorobenzene is less reactive than ethyyl chloride towards nucleophilic substitution reaction

Answer 1

Answer: Chlorobenzene is less reactive towards nucleophilic substitution reaction because of the following reasons: ... This results in delocalization of the electrons of C - Cl bond and a partial double bond character develops in the bond, which makes it difficult for the Nucleophile to cleave the C - Cl bond.
