Alkenes

Question
9 out of 15
 

In the acid catalyzed dehydration reaction of an alcohol, which of the following aspects listed can definitely be true?

A There can be no rearrangement of the intermediate, regardless of the alcohol involved
B There can be rearrangement involved, resulting in less stable intermediates from more stable intermediates
C If possible, the major product is the most substituted product because of its higher stability
D None of the above
Ans. C Since acid-catalyzed dehydration sequence may involve rearrangement depending on the alcohol involved, Choice A is wrong. Choice B is only partially correct. Even though it is true that there can be rearrangement, the process of rearrangement results in more stable intermediates rather than less stable intermediates. The major product is the most substituted product, because the most substituted product translates to higher stability.
