Quizplus · Accepted Answer

The starting material is an alkene with a hydrogen bonded to the carbon adjacent to the carbon-carbon double bond. The reaction conditions suggest that a halogenation reaction is taking place (Br2 in chloroform). Halogenation reactions involve the addition of a halogen atom (-X) to one carbon of the double bond and a hydrogen atom (-H) to the other carbon of the double bond. The product is a vicinal dihalide with the halogen atoms bonded to adjacent carbons. In this case, the product is compound III.
