Question

Which of the following is a tertiary alcohol?

• A. \( \text{CH}_3\text{CH}_2\text{OH} \)
• B. \( \text{CH}_3\text{C(OH)}\text{CH}_3 \)
• C. \( \text{CH}_2\text{OH} \)
• D. \( \text{CH}_3\text{C(OH)}\text{CH}_2\text{CH}_3 \)

Hint:

Tertiary alcohols have the hydroxyl group attached to a tertiary carbon, which is bonded to three other carbons.

Answer 1

The Correct Option is B

Step 1: Understanding tertiary alcohols.
Tertiary alcohols are those in which the hydroxyl group is attached to a carbon that is bonded to three other carbons. Step 2: Analysis of options.
(A) \( \text{CH}_3\text{CH}_2\text{OH} \): This is a primary alcohol because the hydroxyl group is attached to a primary carbon.
(B) \( \text{CH}_3\text{C(OH)\text{CH}_3 \):} Correct — This is a tertiary alcohol because the hydroxyl group is attached to a tertiary carbon.
(C) \( \text{CH}_2\text{OH} \): This is a primary alcohol, as the hydroxyl group is attached to a primary carbon.
(D) \( \text{CH}_3\text{C(OH)\text{CH}_2\text{CH}_3 \):} This is a secondary alcohol, as the hydroxyl group is attached to a secondary carbon.
Step 3: Conclusion.
The correct answer is (B) because the hydroxyl group is attached to a tertiary carbon, making it a tertiary alcohol.
