Question

Chlorobenzene when react with NaCN and CuCN at 473k

Answer 1

Welcome dear,

● Answer -
Benzyl nitrile is formed.

● Rosenmund–von Braun synthesis -
- It is an organic reaction in which an aryl halide reacts with cuprous cyanide to yield an aryl nitrile.
- For example, when chlorobenzene reacts with CuCN/NaCN under pressure at 473 K, benzyl nitrile is formed.
C6H5-Cl + CuCN ---> C6H5-CN + CuCl


Hope this helps you.
Keep asking..

Answer 2

Answer:The products will be:-

C6H5CN + CuCl

Explanation:

Cl of the aryl halide gets replaced by the CN of CuCN with the help if pyridine as catalyst at 475k temperature.
