An organic compound having molecular mass 60 contains C = 20%, H = 6.67%, N = 46.67%, and rest Oxygen. On heating, it gives NH_{3} along with a solid residue that gives a violet color with alkaline copper sulfate. The compound is:

Solution & Step-by-step Explanation

Empirical Formula: Calculations lead to CH_{4} N_{2} O (Molecular mass 60). This matches Urea.Heating Urea: Two molecules of Urea lose NH_{3} to form Biuret.Biuret Test: Biuret gives a violet color with alkaline CuSO_{4} .
