2.A compound (X) having formula C3H7 NO reacts with Br2 in the presence of NaOH to give another compound (Y). Compound (Y) reacts with HNO2 to form ethanol and 
gas . Identify (X) and (Y) . Write the reaction involved.
Ans.
Since Y gives ethanol and gas with
, therefore it is
.
Ethan amine (Y) is formed on reacting (X) with 
and NaOH;
Therefore X is
