Quizplus · Accepted Answer

The dehydration of 2,3-dimethyl-3-pentanol will result in the removal of a water molecule from the hydroxyl group, leading to the formation of a double bond between the C-2 and C-3 atoms. Since the methyl groups at C-2 and C-3 hinder rotation around the C-C double bond, the major product will be the one with the least steric hindrance at C-4. Therefore, the best choice for the major product is option B, which is 2,3-dimethyl-2-pentene.
