A compound Z with molecular formula C3H9N reacts with C6H5SO2Cl to give a solid, insoluble in alkali. Identify Z.


Z is ethylmethylamine.

According to the question, C3H9N reacts with C6H5SO2Cl or Hinsberg’s reagent to give a solid, insoluble in alkali which means that C3H9N is a secondary amine. The product obtained in this reaction has no replaceable hydrogen attached to the nitrogen atom of the amine group.


Thus the structure of given amine is



The chemical reaction involved in this case is:
