Orbitals on carbon:
- Two green p atomic orbitals are shown, one on each carbon ready to form a pi molecular orbital
- Two blue p atomic orbitals are shown, one on each carbon ready to form a second pi molecular orbital at right angles to the first
- a red sigma molecular orbital formed by overlap of two sp atomic orbitals connects the carbons which are not visible in the drawing below
- two additional red sp atomic orbitals are shown at each end and are ready to form sigma molecular orbitals with hydrogen s atomic orbitals
