Question

Which of the following compound does not liberate nitrogen with $HN{O}_2$?

• A. Carbamide
• B. Primary amine
• C. Secondary amine
• D. Alkanamide

Answer 1

The correct option is C Secondary amine

Secondary amines do not read with $HN{O}_2$ to produce $H_2.$

$\Rightarrow R_{2}NH+H-O-N=0\to R_{2}N-N=0+H_{2}O$

Hence, the answer is secondary amines.
