VSEPR V – Valence S – Shell E – Electron P – Pair R – Repulsion It is based on this theory that we understand the three dimensional structure of molecules. VSEPR theory states that repulsion between the sets of valence-level electrons surrounding an atom causes these sets to be oriented...

Molecular Orbital Theory - CO The Lewis structure and valence bond theory suggest to us that CO has a triple bond, with one lone pair of electrons on the oxygen atom and one lone pair of electrons on the carbon atom: It is important to note that: Z eff (O) > Z eff (C) the energ...
