Answer -
The mechanism of the reaction of HI with methoxymethaneinvolves the following steps:
Step1: Protonationof methoxymethane:
Step2: Nucleophilic attack of I−:
Step3:
When HI is in excess and the reaction is carried out at ahigh temperature, the methanol formed in the second step reacts with another HImolecule and gets converted to methyl iodide
