Question

The acid-catalyzed dehydration mechanism for alcohols is best described as a(n) :
Options
A E1
Correct Answer
B E2
C SN1
D SN2
Correct Answer

Option A is the correct answer.

Detailed Explanation

Acid-catalyzed dehydration of alcohols proceeds via an E1 mechanism. The alcohol is protonated, water leaves to form a carbocation, and then a proton is eliminated to form the alkene. The rate-determining step is formation of the carbocation.

Hint

What mechanism involves a carbocation intermediate in elimination reactions?
