1. E10C.5(b): Consider BF3 (point group D3h). There are SALCs from the F valence orbitals which transform as A" and E". Are there any valence orbitals of the central B atom that can have a non-zero overlap with the SALCs? How would your conclusion differ for AlF3, where 3d orbitals might be available? 2.
