Vedclass · Answer

(A) The reaction of amines with benzenesulfonyl chloride $(C_6H_5SO_2Cl)$ is known as the Hinsberg test.$1^{\circ}$ amines $(R-NH_2)$ react with benzenesulfonyl chloride to form $N$-alkylbenzenesulfonamide,which contains an acidic hydrogen atom attached to the nitrogen. This makes it soluble in alkali $(NaOH)$.$2^{\circ}$ amines $(R_2NH)$ react to form $N,N$-dialkylbenzenesulfonamide,which does not contain any acidic hydrogen atom attached to the nitrogen,and thus it is insoluble in alkali.$3^{\circ}$ amines do not react with benzenesulfonyl chloride.In the given options,option $A$ is an $N$-substituted sulfonamide $(R-SO_2NH-R')$,which has an acidic hydrogen on the nitrogen atom,making it soluble in $NaOH$.

Which of the following is soluble in sodium hydroxide $(NaOH)$?
