Lewis Structure of CH3I

The video tutorial explains the process of drawing the Lewis structure for CH3I. It begins by identifying the total number of valence electrons and arranging the atoms with carbon at the center, surrounded by hydrogen and iodine. The tutorial then details the distribution of valence electrons to form chemical bonds and fill the octets of iodine, carbon, and hydrogen. The video concludes by confirming that all valence electrons are used and the octets are complete, resulting in the finalized Lewis structure for CH3I.
