Question

The reaction \( 2R - Cl + CoF_2 \rightarrow 2R - F + CoCl_2 \) is an example of .......

• A. Swarts reaction
• B. Finkelstein reaction
• C. Wurtz – fittig reaction
• D. Sandmeyer’s reaction

Hint:

The Swarts reaction is important for halogen exchange and the formation of organofluorine compounds.

Answer 1

The Correct Option is A

Step 1: Understanding Swarts reaction.
The Swarts reaction involves the replacement of halogen atoms in alkyl halides with another halogen in the presence of a halogenating agent like CoF\(_2\). The reaction shown is characteristic of the Swarts reaction, which typically occurs in alkyl halides.

Step 2: Analyzing the options.
(A) Swarts reaction: This is the correct reaction type as it involves halogen exchange.
(B) Finkelstein reaction: This reaction involves the exchange of halogens between alkyl halides and sodium halides.
(C) Wurtz – fittig reaction: This reaction involves the coupling of alkyl halides or aryl halides.
(D) Sandmeyer’s reaction: This reaction involves the formation of aryl halides via the reaction of aryl diazonium salts with halides.

Step 3: Conclusion.
The correct answer is (A) Swarts reaction.
