Unformatted text preview: formulation to determine the number of electrons that are associated with the pathway. (d) Formulate a basis set that represents the orbital array for the starting structure. (e) In each instance, formulate a cyclic array corresponding to the thermally allowed pathway and determine the number of sign inversions in each array. H 2 C O HO D A B D B/A A/B H H In addition to the parts a-e above, specify the orientation for substituents A and B corresponding to the allowed pathway. Finally, apply your knowledge of nomenclature for bicyclic systems, and determine the nature of the bicyclic framework for this case and the one shown below. H H X X +...
