Which of the following compounds is the major organic product of the reaction conditions shown?

Question

Quizplus · Accepted Answer

The reaction condition shown involves the addition of hydrogen bromide (HBr) to an alkene. This is a classic example of an alkene halogenation reaction. In this particular case, the alkene is a 5-membered ring system with a double bond between the second and third carbons. When HBr adds to this alkene, it will form a new carbon-bromine bond and break the double bond, resulting in a product with the same number of carbons but one more bromine. Looking at the answer choices, the only product with an extra bromine is D, which has a bromine attached to the fourth carbon. Therefore, D is the major organic product that forms under these reaction conditions.
