Comparing Minima: Catechol has three primary in the ring plane distinguishable stationary point conformations with different relative hydroxyl orientations while hydroquinone has only two. a) Identify and image the structures of all these stationary points. Provide RHF energy (in Hartree) for all these structures at the HF/3-216 level. b) Compare the global minimum energies for catechol and hydroquinone. Explain the potential energy difference between these conformers of catechol and hydroquinone.
