Iodomethane (ie-oh-duh-METH-aen) ( ), which is also called methyl iodine, is a methane molecule ( ) in which an iodine atom replaces one of the hydrogen atoms. It is a colorless liquid that is used to synthesize various organic compounds. Follow the steps below to write the Lewis structure for iodomethane. You may use your Periodic Table. Determine the type and number of each atom in the molecule. Number of Carbon atoms: Number of Hydrogen atoms: Number of Iodine atoms: Write the electron dot notation for each type of atom. Carbon: Hydrogen: Iodine: Calculate the total number of available valence electrons. Determine the location of the atoms within the molecule and connect each atom with a shared pair of electrons. Add unshared pairs of electrons. a. 3 b. Lewis structure c. 1 d. Lewis structure e. 16 f. Lewis structure g. Lewis structure h. Lewis structure i. 14 j. Lewis structure k. Lewis structure l.
