Vedclass · Answer

(C) $p$-toluenesulphonyl chloride $(CH_3C_6H_4SO_2Cl)$ is commonly known as Hinsberg's reagent.It is used to distinguish between primary $(1^{\circ})$,secondary $(2^{\circ})$,and tertiary $(3^{\circ})$ amines.$1$. Primary amines react with Hinsberg's reagent to form $N$-alkylbenzenesulphonamide,which contains an acidic hydrogen atom attached to the nitrogen,making it soluble in alkali.$2$. Secondary amines react with Hinsberg's reagent to form $N,N$-dialkylbenzenesulphonamide. This product does not contain any acidic hydrogen atom attached to the nitrogen,so it is insoluble in alkali.$3$. Tertiary amines do not react with Hinsberg's reagent because they lack an acidic hydrogen atom.Therefore,the statement that the product formed with a secondary amine is soluble in alkali is incorrect.
