Question
How will you prepare n propyl iodide from n-propyl bromide?
Advertisements
Solution
n-propyl bromide on heating with a concentrated solution of sodium iodide in dry acetone gives n-propyl iodide. This SN2 reaction is called Finkelstein reaction.
\[\ce{\underset{\text{n – propyl iodide }}{CH3 - CH2 - CH2Br} + NaI ->[Acetone] \underset{\text{n-propyl iodide}}{CH3 - CH2 - CH2}I + NaBr}\]
