Orbitals on carbon:

• two green p atomic orbitals are shown, one on each carbon ready to form a pi molecular orbital
• a red sigma molecular orbital formed by overlap of two sp2 atomic orbitals connects the black carbons
• four additional red sp2 atomic orbitals are shown ready to form sigma molecular orbitals with hydrogen s atomic orbitals
