Vedclass · Answer

(A) The reactivity of alkyl halides towards $SN^2$ reactions is primarily governed by steric hindrance. The order of reactivity is $1^\circ > 2^\circ > 3^\circ$.$(A)$ $Ph-CH_2-CH_2-CH_2-Br$ is a primary $(1^\circ)$ halide with the least steric hindrance at the reaction site.$(B)$ $Ph-CH(CH_3)-CH_2-Br$ is a primary $(1^\circ)$ halide but has a methyl group at the $\beta$-carbon,which increases steric hindrance compared to $(A)$.$(C)$ $Ph-C(CH_3)_2-Br$ is a tertiary $(3^\circ)$ halide,making it the least reactive towards $SN^2$ due to high steric crowding.$(D)$ $Ph-CH_2-CH(Br)-CH_3$ is a secondary $(2^\circ)$ halide,which is less reactive than primary halides.Therefore,the primary halide with the least steric hindrance,$(A)$,is the most reactive.
