HOMO and LUMO of ethylene and 1,3-butadiene for both ground and excited states. Concept introduction: The most important orbitals in molecules for reactivity are the two so called frontier orbitals. These are called the HOMO (highest occupied molecular orbital and LUMO (lowest unoccupied molecular orbital). The HOMO is the highest energy MO that has any electrons in it. Electrons from the HOMO are donated and mostly available for bonding. The LUMO is the next highest energy orbital (it will be empty). It is the lowest unoccupied molecular orbital which can receives electrons.
