2) (29 points total) a. (16 points) Draw the molecule (3R,4R)-3,4-dimethylhexane as well as all unique stereoisomers for the molecule. Utilize the appropriate dashes and wedges to illustrate each stereoisomer. b. (6 points) Are any of the stereoisomers for part a meso compounds? If so, draw them below and indicate why. If no stereoisomers in part a are meso compounds, use the answer N/A and provide an explanation for why (5 points) Are any of the constitutional isomers of aliphatic pentane chiral? Why? c. d. (2 points) For (3R,4R)-3,4-dimethylhexane, sight down the carbon 2- carbon 3 bond to produce a Newman projection with carbon 2 in front, and carbon 3 in the rear. Be sure to have the molecule in its lowest energy conformation around the C2-C3 bond.
