Which statement(s)is/are true of acid-catalyzed alcohol dehydrations?

Question

Quizplus · Accepted Answer

All of the statements are true for acid-catalyzed alcohol dehydrations. Protonation of the alcohol is fast because the alcohol is a good nucleophile and the acid is a good electrophile, so the reaction proceeds quickly. Formation of a carbocation from the protonated alcohol is slow because the carbocation is a high-energy intermediate, and its formation requires the breaking of a strong bond. Rearrangements of less stable carbocations to more stable carbocations are common and are favored because they lead to a more stable intermediate. Finally, loss of a proton by the carbocation is fast because the proton is a good leaving group, and the formation of a double bond is a favorable process.
