Mescaline (see structure X) is a naturally-occuring psychedelic compound isolated from the peyote cactus. If mescaline (X) was partitioned between 3M NaOH and dichloromethane (CH2CI2), would X partition primiarily into the organic layer, aqueous layer, or neither layer? H3CO. „NH2 H3CO mescaline ÓCH3 Organic layer Aqueous layer O Neither layer. X would not partition effectively into either the aqueous or organic layer

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/3-21G level. b) Compare the global minimum energies for catechol and hydroquinone. Explain the potential energy difference between these conformers of catechol and hydroquinone.
