Draw the six conformers in newman projection for the 60 degree intervals from 0 to 360 degrees for carbon atoms 3 and 4. Clearly show which carbon is represented by the "dot" and the "circle" Show which C (dot or circle) is moving and whether it moves clockwise or counterclockwise. Label each as: staggered, eclipsed, anti. Sketch any energy diagram which shows the relative energy of all six conformers
