What hybridization is involved in the carbon-carbon bonds?

A carbon atom can form a covalent bond with another carbon atom, the most common way this is done being through a single bond (or a sigma bond).

In such a case, the sigma bond is formed between one hybridized orbital from each of the two carbon atoms.

In alkanes like ethane, carbon's orbitals are sp3 hybridized - this means that one s orbital and three p orbitals come together to form four sp3 hybrid orbitals. Single bonds can form between carbon atoms with other hybridizations as well (sp2 with sp2, for example).

In alkenes, carbon atoms can form double bonds; these bonds, consisting of one sigma and one pi bond, are formed with an sp2 hybridized orbital and an unhybridized p orbital.

In alkynes, the carbon atoms can form triple bonds; these bonds, consisting of one sigma and two pi bonds, are formed with an sp hybridized orbital and two unhybridized p orbitals.
