Please draw 3D models if possible

Part A: Enantiomers and Diastereomers.

1. Construct a model of Molecule (a), as well as the model of its mirror image. [only molecule BrCH2CH(F)CH3]

Part B: Newman projections. (instead of F and H (on top) left, it is Br H Br)

1. Construct a model of the provided molecule (match the configuration exactly) and look down at the indicated bond.

2. Using your model, construct an energy diagram to show the variation in the free energy of the molecule as the FRONT ATOM is rotated CLOCKWISE from 0 to 360 in 60 increments. In your energy diagram, you should clearly show the relative energies of each conformer.

3. Draw Newman projections for each conformation on the bottom of your diagram.

Part C: Chair conformations (same as picture)

1. Build a model of the molecule in one chair form.

a) FCH2CH(OH)CH3 b) CH3CHClCH(OCH3)CH3 c) CH3OCH(CH3)OCH3 d) Part B Part C
