Which of the following statments is NOT correct for benzene sulfonyl chloride?
Options
- AIt is known as Hinsberg's reagent.
- BIt is use to distiguish primary and secondary amines.
- COn treatement with secondary amines, it leads to product that is soluble in alkali.
- DIt does not react with tertiary amines.
Correct answer
C. On treatement with secondary amines, it leads to product that is soluble in alkali.
Step-by-step solution
Benzene sulfonyl chloride ( C₆H₅SO₂Cl ) is known as Hinsberg's reagent. It reacts with primary amines to form N-alkylbenzenesulfonamide, which contains an acidic hydrogen attached to nitrogen and is therefore soluble in alkali. It reacts with secondary amines to form N,N-dialkylbenzenesulfonamide. Since there is no acidic hydrogen attached to the nitrogen atom, this product is insoluble in alkali. It does not react with tertiary amines. Thus, the statement that it leads to a product soluble in alkali on treatment w
