An organic compound (molar mass = 60) is found to containC= 20%,  H= 6.67% and N=  46.67%.C = {\text{ }}20\% ,\,\,H = {\text{ }}6.67\% {\text{ and}}\,N = \;46.67\% . While rest is oxygen. On heating it gives NH3N{H_3} along with a solid residue. The solid residue gives violet with alkaline CuSO4.CuS{O_4}. The organic compound is:
