Vedclass · Answer

(A) The reaction of alkyl chlorides with acetate in acetic acid proceeds via an $SN^{1}$ mechanism,which involves the formation of a carbocation intermediate. The rate of the reaction is directly proportional to the stability of the carbocation formed.$1$. The first compound forms a tertiary allylic carbocation,which is highly stable due to resonance and hyperconjugation.$2$. The second compound forms a secondary allylic carbocation with an adjacent methyl group,providing stability via hyperconjugation.$3$. The third compound forms a secondary allylic carbocation.$4$. The fourth compound forms a primary allylic carbocation,which is the least stable among the given options.Thus,the order of reactivity is based on the stability of the carbocations: $3^{\circ} 	ext{ allylic} > 2^{\circ} 	ext{ allylic (with } CH_3 	ext{ group)} > 2^{\circ} 	ext{ allylic} > 1^{\circ} 	ext{ allylic}$.The correct order is shown in option $A$.

The correct order of reactivity of the given chlorides with acetate in acetic acid is:
