Quizplus · Accepted Answer

The reaction involves an S*_N*_2 substitution of a primary alkyl halide by a strong nucleophile. The nucleophile attacks the carbon atom bearing the leaving group in the transition state, forming the product. As the product is formed at the site of the leaving group, only one product is expected. It is a rearranged product resulting from the migration of the alkyl group from the beta-carbon to the alpha-carbon. Therefore, the expected product is III. The other options are unlikely to occur because there is no possibility of elimination, and the nucleophile is not strong enough to carry out an S*_N*_1 reaction.
