1.) Carefully draw two very neat cyclohexane chair molecules with the “headrest on the left”. Then draw two very neat cyclohexane molecules with the “headrest on the right”. Use a ruler or straightedge for the lines and try to make the C-C bonds about the same length. The axial and equatorial bonds do NOT need to be shown for this problem. 2.) Carefully draw another cyclohexane chair molecule with the “headrest on the left”. To this drawing, draw all of...
