Question:
Which test is used to distinguish between primary, secondary and tertiary amine?
Which test is used to distinguish between primary, secondary and tertiary amine?
Show Hint
Think of the classic benzenesulfonyl chloride plus KOH test for amines.
Updated On: Jul 3, 2026
- Lucas test
- Hinsberg test
- Baeyer test
- Molisch test
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: The Hinsberg test uses benzenesulfonyl chloride with aqueous KOH.
Step 2: A primary amine forms a sulfonamide with an acidic N-H, dissolving as its potassium salt in KOH.
Step 3: A secondary amine forms a sulfonamide with no acidic N-H, insoluble in KOH.
Step 4: A tertiary amine does not react at all, remaining as an oily layer.
