Quizplus · Accepted Answer

The given reaction sequence involves a syn addition of Br2 to a double bond followed by an SN2 substitution of Br with Cl in the presence of water. This results in the formation of a meso-3,4-dichlorohexane, which has two chiral centers but is not optically active due to internal compensation. Therefore, the final product is a racemic mixture of (2R,3R) and (2S,3S) isomers. Hence, option D is the best choice.
