Bromination of trans-cinnamic acid 1. Why should you add more Br2 to the reaction mixture if it turns colorless during the course of the reaction? 2. Predict the products likely to be formed via the anti- addition of Br2/acetic acid to trans- cinnamic acid. 3. What is the predicted m.p. of the brominated product(s) you prepare vis this method? 4. Draw Fischer projection formulas for the products likely to be obtained from the bromination of (Z)-2-pentene with Br2/acetic acid. Identify the chiral centers with asterisks and label each center as R or S. 5. How might you use 13C NMR spectroscopy to determine if the brominated product is contaminated with some unreacted starting material (during the bromination of trans-cinnamic acid)?
