Pi Bond Molecular Orbital Diagram. The central carbon is sp hybridised. For remaining elements molecular orbitals must also be formed using p orbitals.
Molecular orbital s are for med combining similar atomic orbital s. While a sigma bond is always the first bond between two atoms a pi bond is always the second bond between two atoms and third bond if present. The lowest unoccupied molecular orbitals lumo that can accept the electron density from an appropriately oriented filled metal orbital resulting in the formation of an m c o π bond is π 2 p x π 2 p y.

After forming the sigma bonds with the 2sp2 hybrid orbitals between the atoms each oxygen atom has a remaining 2p orbital for pi bonding. The new hybridized electronic configuration of oxygen atoms is as. Diagram showing the shape of the pi bonding in ethene. First consider the hybridization of the oxygen atoms in ozone.
