Vedclass · Accepted Answer

$ii > iii > i$

Vedclass · Answer

(B) The reactivity of alkyl halides towards $S_N2$ reaction depends on steric hindrance and the stability of the transition state.$(i)$ $CH_2=CH-Cl$ is a vinyl chloride where the $C-Cl$ bond has partial double bond character due to resonance,making it extremely unreactive towards $S_N2$.(ii) $CH_2=CH-CH_2-Cl$ is an allyl chloride. The transition state is stabilized by resonance with the adjacent double bond,making it highly reactive.(iii) $N\equiv C-CH_2-CH_2-Cl$ is a primary alkyl chloride. It is reactive,but less so than the allylic halide due to the lack of resonance stabilization in the transition state.Therefore,the order of reactivity is $ii > iii > i$.

Identify the correct reactivity order for the $S_N2$ reaction for the following compounds:
$(i)$ $CH_2=CH-Cl$
(ii) $CH_2=CH-CH_2-Cl$
(iii) $N\equiv C-CH_2-CH_2-Cl$
