Question

Alkyl chloride when treated with sodium iodide in presence of dry acetone forms alkyl iodide. What is the name of this reaction?

• A. Swarts reaction
• B. Wurtz reaction
• C. Wurtz - Fittig reaction
• D. Finkelstein reaction

Hint:

In the Finkelstein reaction, an alkyl halide undergoes a halogen exchange with a sodium halide (NaI) in acetone to form an alkyl iodide.

Answer 1

The Correct Option is D

Step 1: Understanding the Finkelstein reaction.
The Finkelstein reaction is a halogen exchange reaction in which an alkyl halide reacts with a sodium halide (like NaI) in acetone, leading to the substitution of one halogen with another (e.g., Cl$\to$I).
Step 2: Analyzing the options.
(A) Swarts reaction: The Swarts reaction is a halogen exchange reaction, but it uses chlorine and fluorine as reactants and involves different conditions.
(B) Wurtz reaction: The Wurtz reaction is a coupling reaction between two alkyl halides, not a halogen exchange.
(C) Wurtz - Fittig reaction: This reaction involves both halogenation and coupling, but it is not a halogen exchange reaction.
(D) Finkelstein reaction: This is the correct answer as it specifically describes the halogen exchange between alkyl chloride and sodium iodide in acetone.
Step 3: Conclusion.
The correct answer is (D) Finkelstein reaction.
