Drawing the Molecular Orbital Diagram. Figure 1.9. 2: Structure of methane molecule. Consider CH 4 as a specific example of a molecule within the Td symmetry group. Before drawing the MO diagram, the valence atomic orbitals on the central atom and their symmetries must be noted. The formation of molecular orbitals in ethane Ethane isn't particularly important in its own right, but is included because it is a simple example of how a carbon-carbon single bond is formed. Each carbon atom in the ethane promotes an electron and then forms sp 3 hybrids exactly as we've described in methane.

Determining CH 4 molecular geometry should be easier. In methane, the four hybrid orbitals are located in such a manner so as to decrease the force of repulsion between them. Nonetheless, the four orbitals do repel each other and get placed at the corners of a tetrahedron. CH 4 has a tetrahedral shape. The sp 3 hybrid orbitals have a bond angle ...

The molecular orbital description of bonding in methane does several things for us. It should reconcile our valence-bond idea of electrons localized between carbon and hydrogen with the "delocalized" picture typical of the MO approach. It should tell us (quantitatively) about the energies of different electrons. A molecular orbital diagram showing both the bonding and anti‐bonding molecular energy levels is provided below.

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.
