Valence Electrons and Bonding in COCl2

The video tutorial explains how to draw the Lewis structure for COCl2. It begins by calculating the total valence electrons, placing carbon in the center due to its lower electronegativity, and arranging oxygen and chlorine around it. Initial bonds are formed, and adjustments are made to ensure each atom achieves an octet. A double bond is formed between carbon and oxygen to satisfy the octet rule, resulting in the complete Lewis structure for COCl2.
