Question

The reaction \[\ce{2R-Cl + CoF2 -> 2R-F + CoCl2}\] is an example of ____________.

Options

• Swarts reaction

• Sandmeyer's reaction

• Wurtz-fittig reaction

• Finkelstein reaction

Answer 1

The reaction \[\ce{2R-Cl + CoF2 -> 2R-F + CoCl2}\] is an example of Swarts reaction.

Explanation:

Swart's reaction is exemplified by the following reaction. Alkyl halides are involved in this halogen exchange process. A heavy metal fluoride is employed in this process.

\[\ce{\underset{\text{Alkyl chloride}}{2R-Cl} + CoF2 -> \underset{\text{Alkyl fluoride}}{2R-F} + CoCl2}\]

Alkyl fluoride and corresponding metal chloride are formed when alkyl chloride or alkyl bromide are heated with metallic fluoride (CoF₂).
