Which of the following Newman projections represents (2R,3R)-dibromobutane?
Consider the Newman projection below. a. Draw a full Lewis structure of this molecule with R1=Me,R2=Et , and R3=iPr . b. Given the sizes of these R groups (R3R2R1) , does the Newman projection above show thelowest potential energy conformation of this bond? If not, draw a Newman projectionshowing 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 thumbusually applies: Place the largest group on the front carbon anti to the largest group on theback carbon. Is your answer to the previous question consistent with this rule of thumb?

(b) Draw a Newman Projection of of the meso compound of 2,3-dibromobutane looking down the C2-C3 bond with C2 in front, and label your asymmetric carbons as S or R.
Square planar molecules with formula AB2C2 and octahedral molecules with formulas AB4C2 and AB3C3 feature diastereoisomers. Recall that trigonal bipyramidal geometry features two distinct positions: axial and equatorial. Draw all diastereoisomers for trigonal bipyramidal molecules with formula (a) AB4C and (b) AB3C2. You must indicate the stereochemistry using full and dashed wedges and label all positions as either axial (ax) and equatorial (eq)..
