Updated On: Jun 4, 2025
- NaNO\(_2\) / HCl, 273 – 278 K; Cu\(_2\)Cl\(_2\) / HCl
- NaNO\(_2\) / HCl, 293 – 298 K; Cu\(_2\)Cl\(_2\) / HCl
- NaNO\(_2\) / HCl, 273 – 278 K; SOCl\(_2\)
- NaNO\(_2\) / HCl, 273 – 278 K; Cl\(_2\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Aniline is diazotized using NaNO\(_2\) and HCl at low temperatures (273–278 K) to form a diazonium salt, which then reacts with Cu\(_2\)Cl\(_2\) (Sandmeyer reaction) to form chlorobenzene.
