10 Questions
What is necessary for two atomic orbitals to form effective molecular orbitals?
The AO's must have compatible symmetry
What is the effect of a larger value of SAB on HAB?
HAB increases
What is the result of the energies of EA and EB being significantly different?
The MO's will not differ significantly from the original AO's
Why were the s and p orbitals hybridized in carbon?
To increase the overlap of the charge clouds
What is the rough criterion for the energies of EA and EB to form effective molecular orbitals?
