Series E and F can be viewed as two different ways to annulate an ethano bridge onto four-, five-, and six-membered rings. Using the Hfo values given (in kcal/mol), calculate the strain energy for each compound. Briefly discuss whether the trend seen in each series is consistent with expectations based on additivity of ring strain.
