Question:
Which of the following benzylic alcohol is tertiary alcohol?
Which of the following benzylic alcohol is tertiary alcohol?
Show Hint
For tertiary alcohols, the carbon bearing the hydroxyl group is bonded to three other carbon atoms.
Updated On: Mar 28, 2026
- Phenyl methanol
- 1- phenyl ethanol
- 2- phenyl propan-2-ol
- 1- phenyl propan-2-ol

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding tertiary alcohols.
A tertiary alcohol has a hydroxyl group (-OH) attached to a carbon that is bonded to three other carbon atoms.
Step 2: Analyzing the options.
(A) Phenyl methanol: This is a primary alcohol, as the hydroxyl group is attached to a carbon bonded to one other carbon.
(B) 1- phenyl ethanol: This is a secondary alcohol, as the hydroxyl group is attached to a carbon bonded to two other carbon atoms.
(C) 2- phenyl propan-2-ol: Correct — This is a tertiary alcohol, as the hydroxyl group is attached to a carbon bonded to three other carbon atoms.
(D) 1- phenyl propan-2-ol: This is a secondary alcohol, as the hydroxyl group is attached to a carbon bonded to two other carbon atoms.
Step 3: Conclusion.
The correct answer is (C) 2- phenyl propan-2-ol, as it is a tertiary alcohol.
