The Valence-Bond Description of Polyatomic Molecules

Using LCAOMOs made with hybrid orbitals, describe the bonding and molecular shape of each of the molecules or ions 21.18 Using LCAOMOs made with hybrid orbitals, describe the bonding and molecular shape of each of the molecules or ions  

This wave function corresponds to nonpolar covalent bonds. We can add an ionic term with both electrons on the oxygen atom  

The ionic character of a bond can also be represented by placing an ionic term in each bonding factor instead of making an ionic term for the entire wave function. The space factor of the first bonding factor in the water molecule wave function would become 

Using the valence-bond method, give a description of the bonding in 

The simple wave functions for diatomic molecules obtained in Chapter 20 can be improved by using hybrid orbitals, both in the LCAOMO method and the valence-bond method.
