Vedclass · Answer

(D) The reactivity towards nucleophilic substitution depends on the stability of the carbocation formed or the ease of leaving group departure.In $CH_2=CHCl$,$C_6H_5Cl$,and $CH_3CH=CHCl$,the $C-Cl$ bond has partial double bond character due to resonance,making them less reactive.In $ClCH_2-CH=CH_2$ (allyl chloride),the carbocation formed after the departure of $Cl^-$ is resonance stabilized $(CH_2=CH-CH_2^+)$,making it highly reactive towards $S_N1$ reactions.Additionally,it is a primary alkyl halide with an allylic position,which is very reactive towards $S_N2$ reactions due to the stabilization of the transition state by the adjacent $\pi$-bond.
