1. Use the following structure to draw Newman Projections (each subsequent projection with the back carbon rotated 60" clockwise), Label the projection that is highest in energy and lowest in energy. Explicitly label all H's and CHY's. The arrow denotes the "front" carbon. Use this position to start your first Newman Projection Hae H | 改改改改 2. Finish each Newman Projection to correctly represent the following molecule in the box. OH Br CH3 0月
