Question

The mechanism of dehydration of an alcohol to give an alkene involves formation of :
Options
A Carbonium ions
Correct Answer
B Carbanions
C Free radicals
D Carbenes
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?
