1. Each representation in Figure 1 shows ethane (CH3CH3) in its lowest potential energy (most favorable) conformation. If you have a model set available, make a model of ethane and rotate the single bonds until it is in this conformation. а) Construct an explanation for why this conformation is most favorable. b) Consider the Newman Projection in Figure 1. Newman projections are confusing partly because an imaginary disc is inserted in the drawing to create the illusion of near and far. What single atom of ethane is hidden from view behind this disc? 2. Consider the following Newman Projection of ethane in its least favorable conformation and construct an explanation for why it is so un-favorable. HH

Build a model of methylcyclohexane, and use the model to complete the following Newmanprojections of methylcyclohexane in the chair conformation: a. When the methyl group is in an axial or equatorial (circle one) position, the molecule is inits lowest potential energy conformation. b. Label one Newman projection above anti and the other gauche to describe the relationshipbetween the methyl group and C3 of the ring. c. In general, which is a lower PE conformation, anti or gauche? d.
