Which of the statements below correctly describes the chair conformations of cis–1,3–dimethylcyclohexane? a. The two chair conformations are of equal energy. b. The higher energy chair conformation (least stable) contains one axial methyl group and one equatorial methyl group c. The lower energy chair conformation (most stable) contains one axial methyl group and one equatorial methyl group d. The higher energy chair conformation (least stable) contains two axial methyl groups Please show work for the correct answer.

6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. trans-1,2-Dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis-1,3- dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use the molecular models to find the reasons for...
