Draw the most energetic Newman Projection of CH 3 CH (C 6 H 5 )CH 3. Hint:Not all Newman Projections can form an anti, gauche and eclipsed conformation. If you have no clear large group on one side of the projection, you’ll just be stuck with projections called staggered (not overlapping) and eclipsed (overlapping).

The various projections are just different ways of displaying a three dimensional molecule in two dimensions. They are tools for helping us visualize the molecule and the only time you have to use them would be on a test where they specifically ask you to draw them. That said, Newman projections are useful for figuring out how groups interact when they are bonded to adjacent carbons in a molecule.
