9. If more stable conformation of methylcyclohexane is favored by \( 7.28 \mathrm{KJ} / \mathrm{mol} \), calculate \% availability of more stable chair conformation of methylcyclohexane at room temperature. \( \mathrm{R}= \) universal gas constant \( =8.314 \mathrm{~J} \). \( \mathrm{K}-1 \mathrm{Mol}-1 \) 10. Why is t-butylcyclohexane almost locked in the chair conformation where t-butyl group lies in equatorial position? 11. Predict the equilibrium between chair 1 and chair 2 conformations of the following compounds: Chair 1 cis-1,2-dimethylcyclohexane trans-1,2-dimethylcyclohexane Chair 1 Chair 2 cis-1,4-dimethylcyclohexane Chair 1 Chair 2 trans-1,4-dimethylcyclohexane
