- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: A —
Solution
- Hinsberg reagent is benzenesulfonyl chloride, .
- Primary amines form a sulfonamide soluble in alkali.
- Secondary amines form a sulfonamide insoluble in alkali.
- Tertiary amines do not react with the reagent.
- Hence the answer is (A).
