Which would undergo S_N2 reaction faster in the following pair and why?

Solution

S_n2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps. Primary alkyl halides prefer to undergo S_N2 reactions than tertiary alkyl halides because of less steric hindrance experienced by the approaching nucleophile.

Hence, out of the given pair, (CH₃ –CH ₂– Br ) would undergo S_N2 reaction faster.
