Question
Which of the following statements rigorously and correctly describe the distinctive chemical behavior of various amines towards nitrous acid ($HNO_2$) generated in situ?
💡 Solution & Explanation
Statement A is true; primary aliphatic amines form highly unstable diazonium ions that collapse into carbocations, leading to alcohols/alkenes and $N_2$ release. Statement B is true; aryl diazonium salts are stabilized by extended $\pi$ -conjugation at low temperatures. Statement C is utterly false; secondary amines form characteristic yellow, oily N-nitrosamines, not diazonium salts. Statement D is true; tertiary aliphatic amines simply undergo acid-base neutralization with $HNO_2$ to form soluble salts.
