Vedclass · Answer

(D) The Hinsberg's reagent is $C_6H_5SO_2Cl$ (benzenesulfonyl chloride). It reacts with primary,secondary,and tertiary amines to form different products: $1$. Primary amines form $N$-alkylbenzenesulfonamide,which is soluble in alkali. $2$. Secondary amines form $N,N$-dialkylbenzenesulfonamide,which is insoluble in alkali. $3$. Tertiary amines do not react with the reagent. Because these products have different solubilities in alkali,the Hinsberg's method is primarily used for the separation of a mixture of primary,secondary,and tertiary amines.
