how to do parts a, b, and c
Use the References to access important values if needed for this question.
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 25°C.
(To determine the percent of the more stable chair at equilibrium, first calculate Keg
and then use this value to find the percentage.)
