The CMO model has a universal reference state based on the Woolley/Gerloch ligand field formalism (left). Its performance easily matches VSEPR theory (right) and often surpasses it.

The CMO scheme also works for loads of cases where current models fail.

It is very much a work in progress and I will be populating this web site as time goes by.

Meanwhile, if you want to test yourselves, consider the following.

Q1. Why is the H-F bond energy in diatomic HF (567 kJ/mol) so much larger than the F-F bond energy in F₂ (155 kJ/mol) while the C-F bond energy in CF₄ (485 kJ/mol) is larger than the H-C energy in CH₄ (413 kJ/mol)?

Q2. Why is BeH₂ linear but BaH₂ bent?
