Question

When treating a primary aliphatic amine ($R-CH_2-NH_2$) with nitrous acid ($HNO_2$) generated in situ at ice-cold temperatures, what is the major organic product ultimately isolated?

Answer: A

💡 Solution & Explanation

Aliphatic primary amines react with nitrous acid ($HNO_2$) to yield highly unstable aliphatic diazonium salts. These immediately decompose even at low temperatures to form primary alcohols ($R-CH_2-OH$) along with the vigorous evolution of nitrogen gas.
