$CH_3-CH_2-NH_2$

Vedclass · Answer

(A) The Hinsberg reagent is benzene sulfonyl chloride $(C_6H_5SO_2Cl)$.Primary amines $(R-NH_2)$ react with the Hinsberg reagent to form $N$-alkylbenzene sulfonamide $(C_6H_5SO_2NHR)$.This product contains an acidic hydrogen atom attached to the nitrogen atom,which makes it soluble in alkali (e.g.,$NaOH$).Secondary amines $(R_2NH)$ form $N,N$-dialkylbenzene sulfonamide,which does not contain an acidic hydrogen and is insoluble in alkali.Tertiary amines $(R_3N)$ do not react with the Hinsberg reagent.Therefore,$CH_3-CH_2-NH_2$ (a primary amine) is the correct answer.

Which of the following reacts with Hinsberg reagent to give a product which is soluble in alkali?
