Valence Electrons and Bonding in OCS

The video tutorial explains how to draw the Lewis structure for OCS, starting with the calculation of valence electrons for each atom: Oxygen, Carbon, and Sulfur. Carbon, being the least electronegative, is placed in the center with Oxygen and Sulfur on either side. The tutorial guides through the process of forming chemical bonds, filling octets, and adjusting electron pairs to ensure all atoms achieve a stable configuration. The final structure is achieved by sharing electrons to form double bonds, ensuring the total valence electron count remains at 16.
