Question

Quizplus · Accepted Answer

In order for a dehydration reaction to occur, the alcohol must have a hydrogen atom on the adjacent carbon. Alcohols II and V do not have this, so they cannot undergo dehydration. Alcohol I has a tertiary carbon on the adjacent carbon, so it undergoes elimination instead of dehydration. Alcohols III and IV both have a primary carbon on the adjacent carbon, so they are the most likely to undergo dehydration. Therefore, the best choice is C, III and IV.
