What reagent is used in the Hinsberg test of amines?

A$${ \left( { CH }_{ 3 }CO \right) }_{ 2 }O$$ and pyridine
B$${ C }_{ 6 }{ H }_{ 5 }{ SO }_{ 2 }Cl$$ in aq. $$NaOH$$
Correct Answer
C$$Na{NO}_{2}$$ in aq.$${H}_{2}{SO}_{4}$$
D$${ CH }_{ 3 }$$ (excess) followed by $$AgOH$$

Solution

Benzene sulphonyl chloride is used in Hinsberg's test of amines to form sulfonamides. A primary amine forms a precipitate of N-alkyl benzene sulphonamide with Hinsberg reagent. This precipitate is soluble in alkali.
