Molecular Orbitals of Square-Planar Tetrahydrides | VIPEr This in-class activity walks students through the preparation of a molecular-orbital diagram for methane in a square-planar environment. The students generate ligand-group orbitals (LGOs) for the set of 4 H(1s) orbitals and then interact these with carbon, ultimately finding that such a geometry is strongly disfavored because it does not maximize H/C bonding and leaves a lone pair on C.

XeF4 Lewis Structure, Molecular Geometry, Hybridization ... Mar 03, 2022 · In the XeF4 MO diagram, it is quite clear that the structure of the compound is square planar. It has a distance of 1.95 A° between the Xe and F. This is particularly explained by the valence bond theory, as the two non-bonding electrons from 5p are promoted to the 5d orbital.
