Benzenediazonium chloride is made from aniline and nitrous acid at:
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. Arenediazonium salts are stable only when cold.
2. The nitrous acid is generated in the mixture itself.
3. The reaction is run at 273 to 278 K.
