Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Sandmeyer reaction.

The organic reaction used to convert an aryl diazonium salt into an aryl halide using a copper(I) halide catalyst is called the Sandmeyer reaction.

In this reaction:

  1. Aryl diazonium salts are treated with copper(I) halide (CuX, where X is Cl, Br, or I).
  2. The diazonium group is replaced by a halogen atom.
  3. The copper(I) halide acts as a catalyst in this substitution reaction.

This method is useful for synthesizing aryl halides.
