2. Convert the line structure of 2,3-dimethylpentane into a Newman projection as viewed along the C2-C3 bond (C2 in front, C3 in back). Draw the most stable conformation. Two templates are given with one hydrogen atom drawn in place. Note that only one template leads to the correct answer, therefore use only one of the given templates. t Н. H.

4. For the structure shown below, Part A) Draw the Newman projections and 3-D sawhorse structures corresponding to the lowest and highest energy conformations for rotation around the C2-C3 bond. Draw the Newman projections looking FROM THE C2 CARBON TO THE C3 CARBON (i.e. with the C2 carbon in the "front"). Part B) Determine the energy difference between the lowest and highest conformations, and be sure to clearly show each energy contribution that you are including in your calculation.
