Vedclass · Answer

(C) The $S_N2$ reaction mechanism is a concerted,single-step process where the nucleophile attacks the $\alpha$-carbon from the backside. Steric hindrance plays a crucial role in determining the rate of the $S_N2$ reaction. As the number of alkyl groups attached to the $\alpha$-carbon increases,the steric hindrance increases,making the approach of the nucleophile more difficult. The order of reactivity for $S_N2$ reactions is: $	ext{Primary} > 	ext{Secondary} > 	ext{Tertiary}$. $2-$Chloro$-2-$methylpropane is a tertiary alkyl chloride,which provides maximum steric hindrance,making it the least reactive towards $S_N2$ substitution.

The least reactive alkyl chloride in an $S_N2$ reaction is:
