Problem: The heats of reaction were measured for addition of HBr to cis- and trans-2-butene. Use these data to calculate the energy difference between cis- and trans-2-butene. How does this energy difference compare to that based on heats of hydrogenation (Section 6.3) and heats of combustion (Section 5.6)?

🤓 Based on our data, we think this question is relevant for Professor Oconnor's class at UCSD.
