Molecular Orbital Theory (MO) Section 6.5 Shorthand for MO Diagrams in Complex Systems 1. Each atom in conjugated system has      an ‘s’ orbital.  2. The conjugated system will have as     many MO’s as atomic orbitals. 1. The lowest energy orbital has no nodes. 4. Continue increasing the number of nodes by     one.  The nodes are spaced equally. 1. An MO with mostly bonding interactions is     bonding. 1. An MO with mostly antibonding interactions is     antibonding. 1. An MO with balanced bonding and antibonding     is non-bonding.  Also an MO with node on an atom.
