How can you obtain iodoethane from ethanol when no other iodine containing reagent except NAI is available in the laboratery?

Answer» NaI does not react directly with ethanol. In order to solve the problem, ethanol is first converted into chloroethane by reacting with HCl (g) in the presence of anhy. `ZnCl_(2)` this is then reacted with NaI in the presence of acetone to form
iodoethane by halogen exchange reaction.
`underset("Ethanol")(C_(2)H_(5)OH)+HCl(g)overset(ZnCl_(2)("anhyd"))toC_(2)H_(5)Clunderset(("Acetone"))overset("NaI")tounderset("Iodoethane")(C_(2)H_(5)I`.
