The conversion from M e C l to M e I go through S N 2 mechanism. The best solvent for − C l to − I conversion is usually acetone. It is cheap, polar aprotic, good solubility for N a I and poor solubility for N a C l. I think the reason to use ethanol is just because this reaction is too easy to be picky on solvent. fidelity bank nc cary
