a. Use strain energy increments in the OWL Table Reference (see References button, Strain Energy Increments) to calculate the energy difference between the two chair conformations of the compound below. b. Specify substituent positions (axial or equatorial) in the more stable chair. c. Estimate the percent of the more stable chair at equilibrium at 25C. (To determine the percent of the more stable chair at equilibrium, first calculate Kear and then use this value to find the percentage.) Answers: CH eje HC a. The energy difference is b. In the more stable chair: OH kJ/mol. The isopropyl group is in the i The carboxyl group is in the c. At 25C the equilibrium percent of the more stable chair conformation is approximately 8 position. 8 position. Use the Rfrences to access important values if needed for this question. a.
