Benzyl chloride

Vedclass · Answer

(A) The rate of $S_{N}1$ reaction depends on the stability of the carbocation intermediate formed in the rate-determining step.Benzyl chloride $(C_6H_5CH_2Cl)$ forms a benzyl carbocation $(C_6H_5CH_2^+)$,which is highly stabilized by resonance with the benzene ring.Ethyl chloride $(CH_3CH_2Cl)$ forms a primary carbocation,which is less stable.Chlorobenzene $(C_6H_5Cl)$ does not undergo $S_{N}1$ easily due to partial double bond character between $C$ and $Cl$.Isopropyl chloride $(CH_3CH(Cl)CH_3)$ forms a secondary carbocation,which is less stable than the resonance-stabilized benzyl carbocation.Therefore,benzyl chloride reacts most easily via the $S_{N}1$ mechanism.
