Molecular Orbitals in Conjugated Systems. According to the frontier orbital theory, the chemistry of conjugated π systems is largely determined by the HOMO and LUMO π orbitals in the reactant molecules.The outcome of reactions involving interaction of π orbitals can be rationalized using the concepts of orbital phase and orbital symmetry. A molecular orbital diagram of ethene is created by combining the twelve atomic orbitals associated with four hydrogen atoms and two sp 2 hybridized carbons to give twelve molecular orbitals. Six of these molecular orbitals (five sigma & one pi-orbital) are bonding, and are occupied by the twelve available valence shell electrons.
