Question

In Finkelstein reaction, which reactant are used :

• A. $NaI+C_2{H}_{5}OH$
• B. NaF + acetone
• C. $NaBr+C{H}_{3}OH$
• D. $NaI+C{H}_{3}C{H}_{2}Br$

Answer 1

The correct option is D $NaI+C{H}_{3}C{H}_{2}Br$

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