1. The problem statement, all variables and given/known data Hi folks! :) I have a problem with the following problem. Take any methyl halide and prepare methyl iodide.Choose the appropriate solvent. Now what i know is here we are going by SN2 mech and replacing a halide by iodide ion.But the problem i am facing is how can i replace a other halide by a iodide ion because my book says iodide is the best leaving group among all halides.So i am confused how will this happen. ???
