Which of the following undergoes easy dehydration?
Correct answer: B. 2-Methylpropan-2-ol
- A. 3-Methylbutan-2-ol
- B. 2-Methylpropan-2-ol
- C. Ethanol
- D. Methanol
Explanation
Tertiary alcohols are most easily dehydrogenated followed by secondary and primary alcohols being the most difficult to dehydrogenate. As 2-Methylpropan-2-ol is a tertiary alcohol it will dehydrogenate most easily.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
