Vedclass · Answer

(D) In nucleophilic substitution reactions,the reactivity depends on the stability of the carbocation intermediate (in $S_N1$) or the ease of leaving group departure and steric hindrance (in $S_N2$).$A$,$B$,and $C$ are vinylic or aryl halides where the $C-Cl$ bond has partial double bond character due to resonance,making them very unreactive towards nucleophilic substitution.$D$ $(ClCH_2-CH=CH_2)$ is an allyl chloride. The carbocation formed after the loss of $Cl^-$ is an allyl carbocation $(CH_2^+=CH-CH_2^+\leftrightarrow CH_2=CH-CH_2^+)$,which is resonance-stabilized.Additionally,in $S_N2$ reactions,the allyl position is highly reactive due to the overlap of the $p$-orbital of the transition state with the $\pi$-system of the double bond.Therefore,$ClCH_2-CH=CH_2$ is the most reactive.

Which one of the following is most reactive towards nucleophilic substitution reaction?
