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 Keq,andthenuse un this value to find the percentage.) Answers: a. The energy difference is kJ/mol. b. In the more stable chair: - The phenyl group is in the -. The isopropyl group is in the position. position. C. At 25C the equilibrium percent of the more stable chair conformation is approximately 0 more grosp atsempts remaining Strain Energy for Alkanes Axial Strain Energies for Monosubstituted Cyclohexanes a,b This table gives the sum of the values for the 1,3 diaxial interactions of the substifuent
