MO formation for Li, Be, B, C and N diatomics from n=2 orbitals
MO formation for O, F and Ne diatomics from n=2 orbitals note reversal of energy ordering of p 2p and s 2p orbitals
MO formation HF Only orbitals of similar energy combine. Orientation matters!
MO formation HF Only orbitals of similar energy combine. Orientation matters!
MO formation HF Only orbitals of similar energy combine. Orientation matters! Covalent bond but strongly polarized
Switching Gears entirely… Valence Bond Approach VSEPR Prediction: Bond angles 180 in BeH 2 How is that possible? Where are the orbitals?
Valence Bond Approach Can we use localized bonds? In BeH2, we need two equivalent bonds. Where can they be found?
Valence Bond Approach
