What is the primary product formed when primary aliphatic amines react with nitrous acid (HNO2) at low temperatures (0-5°C)?
A. Stable diazonium salts
B. Aliphatic diazonium salts that rapidly decompose to yield nitrogen gas and alcohols✓ Correct Answer
C. Secondary nitroalkanes
D. Tertiary amines via condensation
💡 Solution & Explanation
Primary aliphatic amines react with nitrous acid at low temperatures to yield unstable aliphatic diazonium salts, which immediately decompose to evolve nitrogen gas and form corresponding alcohols. Alternative choices describe aromatic diazonium stability or alternate condensation pathways that do not apply to aliphatic amines.
