I believe it\'s named Methyl iodide. You wouldn\'t number the C that the Iodine is on because there is only one carbon. Also i think that because there is only one carbon the base name is Iodide instead of the longest carbon chain. Hope this helps! Enjoy. Solution I believe it\'s named Methyl iodide.
