Identify the halogen exchange reaction from the following.

Options

  1. AFinkelstein reaction
  2. BSandmeyer reaction
  3. CFittig reaction
  4. DWurtz-Fittig reaction

Correct answer

A. Finkelstein reaction

Step-by-step solution

Finkelstein reaction: It is an S N 2 reaction (substitution nucleophilic bimolecular reaction) that involves an exchange of one halogen atom for another. It is an organic reaction, which uses an alkyl halide exchange into another alkyl halide through a reaction, wherein the metal halide is used. Reaction with halides: RCl Alkyl   halide +   NaBr → RBr Alkyl   bromide → NaI   RI Alkyl   iodide
