Question:
Which one of the following is a secondary alcohol?
Which one of the following is a secondary alcohol?
Show Hint
Primary alcohol: \(OH\) carbon attached to 1 carbon. Secondary alcohol: attached to 2 carbons. Tertiary alcohol: attached to 3 carbons.
Updated On: Apr 29, 2026
- 2-methylbutan-2-ol
- 3-methylbutan-1-ol
- 2-methylbutan-1-ol
- 3-methylbutan-2-ol
- 2,2-dimethylbutan-1-ol
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
A secondary alcohol has the \(-OH\) group attached to a carbon atom bonded to two other carbon atoms.
Step 1: Check 3-methylbutan-2-ol.
Its structure is: \[ CH_3-CH(OH)-CH(CH_3)-CH_3 \]
Step 2: Check carbon bearing \(OH\).
The carbon carrying \(OH\) is attached to two carbon groups.
Step 3: Conclusion.
Therefore, it is a secondary alcohol.
Step 1: Check 3-methylbutan-2-ol.
Its structure is: \[ CH_3-CH(OH)-CH(CH_3)-CH_3 \]
Step 2: Check carbon bearing \(OH\).
The carbon carrying \(OH\) is attached to two carbon groups.
Step 3: Conclusion.
Therefore, it is a secondary alcohol.
