Lewis Structure of Carbon Dioxide

The video tutorial explains how to draw the Lewis structure for carbon dioxide (CO2). It begins by identifying the valence electrons for carbon and oxygen, then places carbon in the center with oxygen atoms on either side. The tutorial demonstrates how to distribute the 16 valence electrons to satisfy the octet rule, initially forming single bonds and then adjusting to double bonds to ensure all atoms achieve full octets. The final structure is a stable CO2 molecule with double bonds between carbon and each oxygen.
