What is the major organic product obtained from the following reaction?

Question

Quizplus · Accepted Answer

The reaction involves an electrophilic addition of hydrogen bromide (HBr) to an alkene. This results in the formation of a haloalkane (in this case, bromoethane). The major organic product obtained from this reaction will be the one that involves the most substituted carbocation intermediate (the more substituted carbocation is more stable). In this case, the alkene has two carbons, so there are two possible carbocations that could form (a primary carbocation on the first carbon, or a secondary carbocation on the second carbon). Since secondary carbocations are more stable than primary carbocations, the major product will be the bromoethane that results from the addition of HBr to the second carbon, giving two as the answer.
