alleryAt what temperature range do aromatic amines form diazonium salts?
A373 to 378 K
B173 to 178 K
C473 to 478 K
D273 to 278 K
Answer & Solution
Correct answer: D. 273 to 278 K
1. Diazonium salts are unstable if the mixture gets warm.
2. The reaction is therefore run in an ice bath.
3. Aromatic amines react with nitrous acid at low temperatures of 273 to 278 K.
4. So the answer is 273 to 278 kelvin.
