###### Question:

7D. Complete the following Fischer projections for all 4 of your models and assign Rand S to all chiral carbons. Label the pairs of enantiomers and the pairs of diastereomers. COOH COOH COOH COOH НО- -Н Н- СН3 COOH Союн COOH соон
7A. Complete the following Fischer projections for the three tartaric acid isomers. Label the pair of enantiomers, a pair of diastereomers, and the meso isomer. Assign R or S designations to all chiral carbons. COOH COOH COOH HOA HTNA OH У соон Соон COOH When a molecule has two different asymmetric carbon atoms, with no plane of symmetry, it may exist in four optically active forms (two pairs of enantiomers). This can be illustrated with the models just used by replacing the OH on one of the arbon atoms by a CH3 group. There are now four distinct ways of constructing the odels: two pairs of enantiomers. Verify this by constructing one pair of
