A is an unsaturated organic nitrogenous compound. When compound A is completely reduced by nascent hydrogen, it would give a saturated organic nitrogenous compound C₂H₇N. Therefore, the molecular formula of compound B is C₂H₇N.
When compound B is treated with nitrous acid, it gave ethanol. It can be deduced that compound B is an amine, i.e. CH₃CH₂NH₂.
Then, it can be deduced that the compound A is an unsaturated amine with molecular formula C₂H₃N. Hence, compound A is CH≡C–NH₂.
The equations are shown below:

Much more reasonably, the starting compound is acetonitrile: CH3C///N
