An organic compound (molar mass = 60) is found to contain

C = {\text{ }}20\% ,\,\,H = {\text{ }}6.67\% {\text{ and}}\,N = \;46.67\% .

While rest is oxygen. On heating it gives

N{H_3}

along with a solid residue. The solid residue gives violet with alkaline

CuS{O_4}.

The organic compound is:

View answer and explanation
