The cyclohexane derivative shown exists primarily in the more stable of the two available chair conformations. Give the position - axial or equatorial - of each of the three groups shown in the more stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with "ax/eq".
The table of "Axial Strain Energies for Monosubstituted Cyclohexanes" found in the "Strain Energy Increments" section of the Reference tool is useful for answering this question.
Partially Correct
When there is more than one substituent on a cyclohexane ring, the more stable of the two chair conformations is the one which (a) has all substituents equatorial or (b) minimizes the axial steric strain. The axial strain for a variety of substituents is listed in the Reference tool.
