Less reactive than benzyl chloride

Vedclass · Answer

(A) Chlorobenzene is less reactive than benzyl chloride towards nucleophilic substitution reactions.In chlorobenzene,the lone pairs of electrons on the $Cl$ atom are involved in resonance with the $\pi$-electrons of the benzene ring. This gives the $C-Cl$ bond a partial double bond character,making it stronger and harder to break.In contrast,benzyl chloride undergoes nucleophilic substitution more easily because the resulting carbocation is stabilized by resonance with the benzene ring.
