5. The electrons in every molecule or ion with four single bonds to a central atom e.g. CH, hybridized and will have a So, and TiCl, are said to be shape 6. Carbon-oxygen bonds are strong. What is the shape of carbon dioxide? What is the shape of carbonate ion CO,"? Draw Lewis structures and indicate what the hybridation of the carbon atom is in each. (Remember carbon always forms four covalent bonds.)
