Vedclass · Answer

(C) The reactivity toward $S_{N}2$ reaction depends on steric hindrance and the stability of the transition state.$(P)$ $CH_2=CH-Cl$ is a vinyl halide where the $C-Cl$ bond has partial double bond character due to resonance,making it highly unreactive toward $S_{N}2$.$(Q)$ $CH_3-CH_2-Cl$ is a primary alkyl halide with minimal steric hindrance.$(R)$ $CH_3-O-CH_2-CH_2-Cl$ is a primary alkyl halide where the oxygen atom provides an electron-withdrawing inductive effect ($-I$ effect),which stabilizes the transition state of the $S_{N}2$ reaction,making it more reactive than a simple primary alkyl halide.$(S)$ $C_6H_5-CH_2-Cl$ is a benzyl chloride. The transition state is stabilized by resonance with the phenyl ring,making it highly reactive toward $S_{N}2$.Comparing these,the order of reactivity is $S > R > Q > P$.

The relative reactivity of the following halides toward $S_{N}2$ reaction follows the order:
$(P)$ $CH_2=CH-Cl$
$(Q)$ $CH_3-CH_2-Cl$
$(R)$ $CH_3-O-CH_2-CH_2-Cl$
$(S)$ $C_6H_5-CH_2-Cl$
