Vedclass · Answer

(C) $1$. Primary amine $(RNH_2)$ reacts with $C_6H_5SO_2Cl$ to form $N$-alkylbenzenesulfonamide $(RNHSO_2C_6H_5)$.$2$. This product contains an acidic hydrogen attached to the nitrogen atom,so it dissolves in aqueous $KOH$ to form a water-soluble potassium salt,$RN(K^+)SO_2C_6H_5$.$3$. Upon acidification of this solution,the potassium salt is converted back into the insoluble $N$-alkylbenzenesulfonamide $(RNHSO_2C_6H_5)$,which appears as a precipitate.

$RNH_2$ reacts with $C_6H_5SO_2Cl$ (Hinsberg reagent) in aqueous $KOH$ to give a clear solution. On acidification,a precipitate is obtained which is due to the formation of:
