can any body help me to answer this question? Comoplete hydrogenation of 1,3,5,7-cyclooctatetraene is exothermic by -101 kcal/mole. Hydrogenation of cyclooctene proceeds with delta H equal to -23kcal/mol. On the basis of these data, would you call cyclooctatetraene armotic? Justify your anser. Would you expect more than one distinct isomer of 1,2-dimethylcyclooctatetrane to exist? If so, explain our reasoning.
