Question

Quizplus · Accepted Answer

The product is formed via the more/most stable carbocation because the electrophile will attach to the carbon with the greatest positive charge. The formation of a stable carbocation intermediate is favored over less stable carbocation intermediates, and the more stable carbocation intermediate will lead to the more stable product. Therefore, the product predicted by Markovnikov's rule is usually the more/most stable product. The other options (A, B, D, and E) are not necessarily true in all cases.
