3. Determine whether the following statements are true or false. Completely fill in the circle in front of your chosen answer. (a) A compound with a plane of symmetry must be achiral. (b) A compound with two or more stereocenters must be chiral. (a) O True O False True O False
For the following molecules, draw all possible stereoisomers using line-angle formulas with wedge/dash notation. Label the stereocenters as R or S. Indicate which ones are enantiomers and which ones are diastereomers. (Remember: there are 2 stereoisomers possible for a molecule with n chiral centers) (A) (B) (C) (1 chiral center) Br OH (2 chiral centers) CI OH CH3 (3 chiral centers)
18. draw the mirror image or the compound shown, then determine whether the compound is chiral or achiral. For each structure containing a six-membered ring, consider a single chair conformer
Draw the molecule shown and one of its diastereomers. Then label the chiral centers on each molecule with their proper stereochemical designation. Upload and embed your drawing.

ITEM #5 (Everyone should look at this question). Consider the two Fischer projections shown at right. They CH CH are NOT of the same molecule. H- -HO- HO In a short paragraph, explain why the molecules shown are NOT the same. OH но- H. HO. но In your explanation, describe how the groups of a Fischer projection are positioned in the ACTUAL molecule (Are the molecules flat in real life, or three-dimensional in real life? If three-dimensional, where exactly are the Hs and OHs positioned when one interprets these projections?) H- HO но H- CH,OH ČH;OH Also in your explanation, describe why the second molecule is not simply the first molecule flipped over (like a pancake).
Draw mirror images for these molecules. Are they different from the original molecule? (a) (b) • Use the wedge/hash bond tools to indicate stereochemistry where it exists.

Several compounds are shown below. For each, make two models: one model of the compound as shown, and the other where each tetrahedral stereocenter is inverted. Compare the two models side-by-side to see if the model with the inverted stereocenter(s) is the enantiomer, or if it is identical to the original. Remember, you can rotate around o-bonds to place the molecule in the conformation with the highest symmetry. Is each compound meso or not?
