How can you obtain iodoethane from ethanol when no other iodine containing reagent except `NaI` is available in the laboratory?

Text Solution

Verified by Experts

Ethanol is treated with red phosphorous and bromine mixture and the product formed will be bromoethane. The bromoethane so formed is then treated with Nal to give iodoethane.
`CH_(3)CH_(2)Ohoverset("RedP"//Br_(2))toCH_(3)CH_(2)Br`
`CH_(3)CH_(2)Broverset(Nal)toCH_(3)CH_(2)l+NaBr`
This reaction is known as Finkelstein reaction
