Question

10. What is the action of NaI on Bromoethane? give the reaction or i will report the answer

Answer 1

Answer:

This operates by the SN2 mechanism. The iodide ion is a reasonably good nucleophile, and adds as I−. Explanation: R−Cl+Na+I− → R−I+N aCl↓.

Explanation:

This operates by the sodium iodide is much more soluble than sodium chloride in acetone, when you do this you see a glassy precipitate of sodium chloride in the acetone. I think there is a named organic spot test for this reaction (its name escapes me at the moment, I should not have finished that bottle of wine last night!). If you have time in an organic laboratory it would be worth your while to do this reaction in a small test tube so you can notice the turbidity of the sodium chloride when it precipitates.
