Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
p-Toluenesulphonyl chloride is used in Hinsberg test to distinguish primary, secondary and tertiary amines.
Step 1: Recall Hinsberg reagent.
Hinsberg reagent is: \[ p\text{-toluenesulphonyl chloride} \]
Step 2: Use of reagent.
It reacts differently with primary, secondary and tertiary amines.
Step 3: Conclusion.
Thus, it can distinguish between secondary and tertiary amines.
