cyclohexane derivatives exist primarily in the most stable of the available chair conformations. give the position, axial or equatorial, of each of the three groups shown when the ring is in the most 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.
