Unformatted text preview: gauche and anti conformations, as well as the conformation in which the two methyls are eclipsed. Make careful sawhorse and Newman projection drawings of the three conformational isomers. b. State which conformational isomer, gauche or anti , would have 0.9 kcal/mol higher energy. Explain your reasoning. 5. Make a molecular model of methylcyclohexane, and carefully draw the two chair conformations. Measure the distance between the methyl carbon and the carbons at the 3- and 5- positions on the ring. On the basis of your measurements, which of the two cyclohexane conformations do you predict will predominate at equilibrium? Is the methyl group axial or equatorial in the more stable conformation? Explain your reasoning. CH 3 3 5...
