Question

The conversion of ethyl bromide to ethyl iodide using sodium iodide and dry acetone, this reaction is known as:

• A. Swartz reaction
• B. Finkelstein reaction
• C. Halogenation
• D. Wurtz reaction

Answer 1

The correct option is B Finkelstein reaction

The Finkelstein reaction is an organic reaction where an alkyl halide is converted into another alkyl halide by reacting with NaI in presence of dry acetone.
$\underset{\text{Ethyl Bromide}}{C_2{H}_{5}Br}+NaI\underset{\text{Heat}}{\overset{\text{Dry Acetone}}{\to }}\underset{\text{Ethyl Iodide}}{C_2{H}_{5}I}+NaBr\downarrow$
This reaction is known as " Finkelstein Reaction"
