Question

Quizplus · Accepted Answer

NBS is a source of bromine radicals, which can abstract a hydrogen from the allylic position of the alkene. This will form a radical, which can then react with a bromine molecule to form the final product. The reaction requires light to initiate the radical formation step. The other reagents listed do not provide a source of radicals or are unlikely to react with the substrate to form the desired product.
