Methane is generally depicted as containing an sp3-hybridized carbon with four equal sigma bonds to four hydrogen atoms. Under the hybridization model, the four valence atomic orbitals (AOs) on carbon are pooled and mixed to form four new (hybrid) AOs - the sp3 hybrids. These four sp3 hybrids overlap with four s orbitals from the hydrogens. In total, eight AOs are used in the bonding model, and eight molecular orbitals (MOs) form the molecule. The eight MOs consist of four bonding MOs (the sigma bonds) and four anti-bonding MOs (sigma-star orbitals). These eight MOs are filled with the eight valence electrons of methane. The eight electrons fill the four bonding MOs (two electrons per orbital) and the anti-bonding MOs remain empty. Under the hybridization model, we predict a bond angle of 109.5 degrees. The experimental value in methane is 109.5. Unfortunately, there is also experimental data on methane that does not agree with the hybridization model. We therefore need to look for a better model for bonding in methane.
