Consider the Newman projection below.

a. Draw a full Lewis structure of this molecule with R₁ = Me, R₂ = Et, and R₃ = i-Pr.

b. Given the sizes of these R groups ( R₃>R₂>R₁), does the Newman projection above show the lowest potential energy conformation of this bond? If not, draw a Newman projection showing the lowest P.E. conformation (sighting down this same bond).

c. To draw a Newman projection in the lowest P.E. conformation, the following rule of thumb usually applies: Place the largest group on the front carbon anti to the largest group on the back carbon. Is your answer to the previous question consistent with this rule of thumb?
