3. Observations, Data & Results: Record your observations, data, and results. a. Data: trans-cinnamic acid: 1.545 grams product: 1.482 grams 4. Calculations: a. 1.545 g trans-cinnamic acid was measured out. How many mmols is this? b. Using the data given in the "DATA" section above, determine the theoretical and percent yields. 5. Equation: Write the overall equation for the reaction. Draw structures (Don't just give formulas) 6. Conclusion section: a. What is the limiting reactant? How do you know? b. Why is bromine added each time the solution's color has faded to a light orange color? c. What is the purpose of adding cyclohexene at the end of the reflux/heating period? d. What is the product? How do you know? e. Does the reaction occur via syn or anti addition? Explain. f. What are flavonoids? (See Lehman pages 200-201.) g. Two enantiomers are possible in the reaction. Draw the two enantiomers. Label all the stereocenters as Ror S. (Number the carbons so that "C1" is the aldehyde group.) h. Draw a mechanism for each of the two addition reactions above, using curved arrow notation. (le: You will have two mechanisms - one for each enantiomer.)
