Handout on Conjugation Chem 335 October 21, 2009 Molecules with high-energy filled orbitals that are adjacent to low-energy empty orbitals can be stabilized by conjugation . Conjugation is the interaction between a filled orbital and an empty orbital to generate a more stable orbital. This interaction is similar to that used to form bonding and antibonding orbitals. Warning: This procedure is only an approximation of the true molecular orbital picture. It is more accurate than the simple molecular orbital diagrams you know how to draw, but less accurate than the calculated molecular orbitals. 1. Begin by constructing a simple molecular orbital diagram by determining the hybridization of all atoms in the molecule and forming sigma and pi bonds as needed. 2. Identify high energy filled orbitals and low energy unfilled orbitals that are capable of conjugative interaction. To have a significant conjugative interaction, the orbitals must: a.
