Vedclass · Answer

(B) $S_N1$ reactions proceed via a planar carbocation intermediate.For a racemic mixture to be formed, the starting alkyl halide must be chiral.In $2$-bromobutane, the carbon atom attached to the bromine is chiral (bonded to four different groups: $-H, -CH_3, -C_2H_5, -Br$).Upon hydrolysis, the leaving group departs to form a planar carbocation, which can be attacked by the nucleophile from either side with equal probability, resulting in a racemic mixture.

In $S_N1$ reaction, the alkyl halide that on hydrolysis produces a racemic mixture is
