Question

The reaction, ${{C}_{6}}{{H}_{5}}{{N}_{2}}Cl\xrightarrow{C{{u}_{2}}C{{l}_{2}}/HCl}{{C}_{2}}{{H}_{5}}Cl+{{N}_{2}}\uparrow$ is called:

• A. Sandmeyer reaction.
• B. Gattermann reaction
• C. Gattermann-Koch reaction
• D. Lederrer Mannase reaction

Answer 1

Answer: (A)

Sandmeyer reaction.

Answer 2

The correct option is(A): Sandmeyer reaction.

The given reaction, involving the conversion of an aryl diazonium salt (C 6​ H 5​ N 2+​ Cl −) into a halogenated aromatic compound using copper(I) chloride (Cu 2​ Cl 2​) as a catalyst and hydrochloric acid (HCl) as a reagent, is indeed the Sandmeyer reaction.

So, the correct option is: Sandmeyer reaction.
