Question

Alkyl iodides are often prepared by the reaction of alkyl chlorides/ bromides with $NaI$ in dry acetone. This reaction is known as

• A. Sandmayer's reaction
• B. Finkelstein reaction
• C. Markovnikov’s reaction
• D. Swarts reaction

Answer 1

The correct option is B Finkelstein reaction

Alkyl iodides are often prepared by the reaction of alkyl chlorides/ bromides with $NaI$ in dry acetone. This reaction is known as Finkelstein reaction.

$R-X+NaI\stackrel{\text{dry acetone}}{\to }R-I+NaX$ $(\because X=Cl,Br)$
