Homework Answers
the above reaction is an example of nucleophilic substitution reaction in which I- is replaced by OH- resulting in the formation of methanol from methyl iodide. hence the nucleophile is H2O.
the mechanism of the reaction is SN2 ( substitution nucleophilic bimolecular) and is given in the picture attached.
