Identify the compound that will react with Hinsberg's reagent to give a solid which dissolves in alkali.Primary amines react with Hinsberg's reagent (benzenesulphonyl chloride) to give an N-alkylbenzenesulphonamide, which is a solid soluble in alkali (it has an acidic N–H).
$CH_3CH_2NH_2 + C_6H_5SO_2Cl \rightarrow C_6H_5SO_2NHCH_2CH_3 + HCl$
So the compound is the primary amine, ethylamine ($CH_3CH_2NH_2$).
