Question:
Which of the following react with Hinsberg reagent?
Which of the following react with Hinsberg reagent?
Show Hint
When testing with Hinsberg reagent, primary and secondary amines typically react to form sulfonamides, while tertiary amines and aniline do not.
Updated On: Jan 23, 2025
- Aniline
- N,N-Dimethyl aniline
- Methyl amine
- C₆H₅NH C₆H₅
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Hinsberg reagent (benzene sulfonyl chloride) reacts with primary amines to form sulfonamides, which are soluble in alkaline solutions. Secondary amines, like methylamine, also form sulfonamides, but these are not soluble in alkaline solutions. Tertiary amines and aniline do not react with Hinsberg reagent.
- Option (A) Aniline: Reacts with Hinsberg reagent.
- Option (B) N,N-Dimethyl aniline: Does not react.
- Option (C) Methyl amine: Reacts with Hinsberg reagent.
- Option (D) C₆H₅NH C₆H₅: Does not react.
Thus, the correct answer is A and C only.
