- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: A —
Solution
- Primary amines react with to form N-alkylbenzenesulfonamide, which is soluble in alkali.
- Secondary amines form N,N-dialkylbenzenesulfonamide, which is insoluble in alkali.
- Tertiary amines do not react with .
- Hence the answer is (A).
