Solution

Correct Answer:

Halogen exchange

The Finkelstein Reaction is a specific method for preparing alkyl iodides from alkyl chlorides or bromides.

  • Reaction: (where )
  • Mechanism: It follows an pathway.
  • Driving Force: Sodium chloride and sodium bromide are insoluble in dry acetone and precipitate out. This shifts the equilibrium forward according to Le Chatelier's principle.
  • This is a classic example of Halogen Exchange.

This easy difficulty chemistry question is from the chapter organic compounds containing halogens, covering the topic of finkelstein reaction. It appeared in the 2025 exam.
