Textbook QuestionUsing the data obtained in Problem 85, calculate the amount of steric strain in each of the chair conformers of 1,1,3-trimethylcyclohexane. Which conformer predominates at equilibrium?449views
Textbook QuestionUsing the data obtained in Problem 81, calculate the percentage of molecules of trans-1,2-dimethylcyclohexane that will have both methyl groups in equatorial positions.343views
Textbook Question(••) The A value of a substituent on a cyclohexane ring is essentially the ∆G° for a substituent going from the equatorial to the axial position in a chair–chair interconversion. Because most substituents prefer to be in the equatorial position, A values are, by definition, positive numbers. Use the table of A values to calculate ∆G° and K_eq for the chair–chair interconversions shown. (b)526views
