Vedclass · Answer

(A) $S_N2$ reactivity depends on the steric hindrance and the stability of the transition state.$(i)$ $CH_3COCH_2Cl$ is an $\alpha$-halo ketone. The carbonyl group is electron-withdrawing and stabilizes the transition state through resonance/inductive effects,making it highly reactive towards $S_N2$.(ii) $CH_2=CH-CH_2Cl$ is an allyl chloride. The transition state is stabilized by conjugation with the $\pi$-bond,making it more reactive than a simple primary alkyl halide.(iii) $CH_3CH_2CH_2Cl$ is a simple primary alkyl halide.Therefore,the reactivity order is $(i) > (ii) > (iii)$.

The correct reactivity order for $S_N2$ reaction is:
$(i)$ $CH_3COCH_2Cl$
(ii) $CH_2=CH-CH_2Cl$
(iii) $CH_3CH_2CH_2Cl$
