Which of the following amines, upon treatment with an aqueous solution of nitrous acid () at low tem — Amines Chemistry Question

💡 Solution & Explanation

Secondary amines (both aliphatic and aromatic), such as N-methylethanamine, react with nitrous acid to yield N-nitrosamines ($R_2N-N=O$). These generally separate from the aqueous reaction mixture as characteristic yellow oily liquids. Primary amines give alcohols/$N_2$ or diazonium salts, while tertiary aromatic amines undergo ring nitrosation.
