On a separate sheet of paper, draw the two alternative chair
conformations for the product formed by the addition of bromine to
4-tert-butylcyclohexene. The Gibbs free-energy differences between
equatorial and axial substituents on a cyclohexane ring are 21
kJ/mol for tert-butyl, and 2.3 kJ/mol for bromine. Calculate the
ratio of the two observed products at 46.0 °C using the following
equation: The gas constant, R, is 8.314 J/K·mol. (Enter your answer

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.
