Methane's MOs have a topology similar to the AOs of carbon, but the structure can be very difficult to visualise, so the methane MO construction diagrams A, B and C (below) are shown with the AOs and MOs superimposed upon line structures of the methane. Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms.It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite.

Properties and bonding. 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.

Introduction to Molecular Orbital Theory
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.
Ethane. • As molecules get bigger constructing the molecular orbitals. becomes more challenging. • Insights into bonding of larger molecules can be attained by. combining fragments with well defined MO's... through orbital. mixing. • In this manner, ethane can be constructed from MO's of two. pyramidal CH3 groups.
