Substituted cyclohexanes Newman projection

Structural Considerations.—The crystal structure of the asymmetrically substituted cis, trans-2,5-di-t-butylcyclohexyl toluene-p-sulphonate (l)has been determined. The mean torsion angle of the cyclohexane ring in (1) is 55.1°, slightly less than the value of 55.9° for cyclohexane. Newman projections along the C-2—C-7 and C-5—C-11 bonds... 

For example, chemists are required to interpret diagrams of a molecule of cyclohexane, or of substituted cyclohexanes, when it is represented as a flat-looking hexagonal projection, or as a side-on view to show the chair form, or as a Newman projection (Fig. 1.8).
