Determine the ratio of the more stable chair conformation to the less stable conformation at equilibrium at 298 K for the following compounds: bromocyclohexane and methylcyclohexane.
The change in the free energy on flipping from the cyclohexane conformer with the designated substituent equatorial to the conformer with the substituent axial:
Bromine, Br: 2.30 kJ/mol
Methyl, CH3: 7.11 kJ/mol
