Vedclass · Answer

(D) The reactivity of alkyl halides towards nucleophilic substitution depends on the stability of the carbocation intermediate (in $S_N1$) or steric hindrance (in $S_N2$).Benzyl chloride $(C_6H_5CH_2Cl)$ is highly reactive due to the resonance stabilization of the benzyl carbocation.Ethyl chloride $(C_2H_5Cl)$ is a primary alkyl halide and is less reactive than benzyl chloride.Chlorobenzene $(C_6H_5Cl)$ is the least reactive due to the partial double bond character of the $C-Cl$ bond caused by resonance.Therefore,the correct order of reactivity is $C_6H_5CH_2Cl > C_2H_5Cl > C_6H_5Cl$.Thus,the reactivity of ethyl chloride is less than that of benzyl chloride.

The reactivity of ethyl chloride towards nucleophilic substitution is:
