given: (i) (iii) (iv) Which one is more stable? Briefly explain your answer. Use a suitable formula to estimate the amount of conformers (in percent) in which the methyl group is in axial and equatorial position at 298 K. Estimate also the energy that would be needed to have a ratio of 99.9% to 0.1%. What is the meaning of the calculated percentage of each particular conformer?
