A compound Z with molecular formula C3H9N reacts with C6H5SO2Cl to give a solid, insoluble in alkali. Identify Z.
Identifying the compound Z
Benzene sulphonyl chloride (C6H5SO2Cl), which is also known as Hinsberg reagent, reacts with primary and secondary amines to form sulphonamides.
In the reaction with secondary amine, sulphonamide formed is N,N−dialkyl benzene sulphonamide. It does not contain any hydrogen atom attached to nitrogen atom. So it is not acidic and hence insoluble in alkali. Hence, Z must be a secondary amine i.e. N−Methylethanamine.
