Vedclass · Answer

(B) The reactivity of alkyl halides towards $S_N2$ mechanism follows the order: $Primary > Secondary > Tertiary$.This order is primarily governed by steric hindrance,where less hindered substrates are more reactive.- Option $A$ is a secondary alkyl halide.- Option $B$ is a primary alkyl halide $(CH_3-CH(CH_3)-CH_2-CH_2-Br)$.- Option $C$ is a secondary alkyl halide with significant steric hindrance.- Option $D$ is a secondary alkyl halide.Since $S_N2$ reactions are highly sensitive to steric bulk,the primary alkyl halide in option $B$ is the most reactive.

Which among the following is most reactive via $S_N2$ mechanism?
