So this compound is composed of two carbon atoms and two H atoms. The bonds between the carbon and the H are one SSP hybridized. And the bond, a sigma bond between the two carbon atoms is SPSP hybridized. Now, these two other bonds are the two Pi bonds, as we'll see in just a second. So let's try to build our molecular orbital diagram for this compound using the atomic orbitals of the individual atoms. So once again, we have our two H atoms.
