They contain two nodal planes. The MO'sof元4and元sare as antibonding as2and元3 are bonding. Ch16 Aromatic Compounds(landscape).docx page 11 Ch16 Aromatic Compounds (landscape).docx page 11 The next two lowest energy MO's are 4 * and 5 * . These are also degenerate orbitals with overall a net two antibonding interaction (4 * has two non-bonding interactions, and two anti-bonding interactions; 5 * has two bonding and 4 anti-bonding interactions). They contain two nodal planes. The MO's of 4 * and 5 * are as antibonding as 2 and 3 are bonding
