Problem 2. Construct a model of propane. Look down the axis of the C(1)-C(2) bond-C(1) should be the front carbon. Arrange the model in the staggered conformation A.
Now, keeping the front carbon, C(1), and its attached hydrogens stationary, make a rotation of 60° about the C(1)-C(2) bond. Sketch Newman projection B of the conformation which results. Rotate another 60° about the C(1)-C(2) bond and sketch Newman projection C of the resulting conformation. Continue rotating 60° until conformations D, E and F result and sketch Newman projections of each.
Are all of the staggered conformations of propane of equal potential energy?
Are all of the eclipsed conformations of propane of equal potential energy?
