As the result of the interaction between the metal d and ligand orbitals, bonding, non-bonding and anti-bonding complex molecular orbitals are formed.

Ethene has \(sp^2\) hybridization, yielding a planar structure with one sigma and one pi bond. In contrast, ethyne has \(sp\) hybridization, resulting in a linear shape with one sigma and two pi bonds.
