Orbital electron density distributions and momentum distributions of both core and valence space of methane are studied quantum mechanically, using RHF/TZVP and B3LYP/TZVP models, respectively. The three molecular orbitals (MOs) of methane in the ground electronic state (X 1 A 1 ), namely, the core MO, 1 a1 and the valence MOs, i.e. 2 a1 and three-fold energy degenerate MOs 1 t2, are studied in both coordinate space and momentum space.

Methane is a tetrahedral molecule with four equivalent C-H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the four hydrogen atoms.

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.
