# What is the hybridisation of hydrogen in methane? [duplicate]

I am trying to understand hybridisation. In methane carbon has $\mathrm{sp^3}$ hybridisation, but what is the hybridisation of hydrogen? Is it $\mathrm{sp^3}$? If yes then why?

• What orbitals does hydrogen have available for bonding? – bon Jun 26 '16 at 9:27
• Orbitals of hydrogen atoms aren't hybridised in $\ce{CH4}$ at all: 1$\mathrm{s}$ orbital of each hydrogen atom forms a $\sigma$-bond with one of the four $\mathrm{sp^3}$-hybridised orbitals of the carbon atom. – Wildcat Jun 26 '16 at 9:28
• Also, per calculations and experimental data, you could also argue for an unhybridised carbon since there are two different energies of the binding MOs. – Jan Jun 26 '16 at 16:56

Hydrogen does not hybridise, as it only has one $s$ orbital. Hybridisation is the "mixing of $s$ and $p$ orbitals; here is a good explanation (for ethane, but it explains the general theory as well).
