The truth is: in reality, sigma bonds, bond orders and hybridization do not exist (not even bonds or orbitals do). They are just concepts to explain the reactivity, stability and geometry of a molecule (and in the case of orbitals to build approximate many-particle wave functions). There is thus no way to compare a sigma-bond strength without choosing some model which introduces bias.In order to understand the hybridization of CH 4 (methane), we have to take a look at the atomic orbitals which are of different shape and energy that take part in the process.
