Which of the following reaction represents swarts reaction?

The Swarts reaction is a chemical process in which alkyl bromides or alkyl iodides react with metallic fluorides to produce alkyl fluorides. This reaction is a significant method for synthesizing fluoroalkanes, compounds that play a crucial role in various chemical and industrial applications.

Reaction Mechanism

In the Swarts reaction, alkyl bromides or iodides are treated with metallic fluorides such as silver fluoride (AgF), cobalt fluoride (CoF₂), or mercury fluoride (HgF₂). The metallic fluorides facilitate the exchange of the halide group (bromide or iodide) with fluorine, resulting in the formation of the corresponding alkyl fluoride.

Chemical Equation

An example of the Swarts reaction can be represented as follows:

CH₃-CH₂-Br + CoF₂ → CH₃-CH₂-F + CoBr₂    

In this reaction, ethyl bromide (CH₃-CH₂-Br) reacts with cobalt fluoride (CoF₂) to form ethyl fluoride (CH₃-CH₂-F) and cobalt bromide (CoBr₂).

Applications of Swarts Reaction

• Used for the preparation of fluoroalkanes, which are essential in the pharmaceutical and agrochemical industries.
• Widely employed in the synthesis of refrigerants and fluorinated polymers.
