Question
The mechanism of dehydration of an alcohol to give an alkene involves formation of :
Correct Answer
Option A is the correct answer.
Detailed Explanation
The acid-catalyzed dehydration of alcohols to alkenes involves formation of a carbocation (carbonium ion) intermediate. The protonated alcohol loses water to form a carbocation, which then loses a proton to give the alkene.
Hint
What intermediate is formed in acid-catalyzed dehydration?
