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.
