Question

Why acetone is used as reagent in finkelstein reaction?

Answer 1

Answer:

Finkelstein reaction is used to prepare alkyl iodides starting from alkyl chlorides and alkyl bromides. In this reaction alkyl chlorides or bromides are treated with NaI in presence of acetone to form alkyl iodides. In acetone, NaI is soluble ,as its lattice energy is lesser than the solvation energy of acetone.
