When trans-cinnamic acid reacts with bromine, the product is 2,3-dibromo-3-phenylpropanoic acid. You measure out 0.30 g of trans-cinnamic acid, 10 mL of dichloromethane, and a 0.5M solution of bromine. When the reaction is finished, you have 0.223 grams of 2,3-dibromo-3-phenylpropanoic acid. A. How many moles of trans-cinnamic acid was used? B. What is the limiting reagent? C. What is the theoretical yield (in moles)? D. What is the actual yield (in moles)? E. What is the total percent yield?

Discuss the differences observed in the IR and NMR spectra of (E)-cinnamic acid and 2,3-dibromo-3-phenylpropanoic acid that are consistent with addition of bromine to the double bond.

Draw the two emanations of 2,3-dibromo-3-phenylpropanoic acid

In the bromination reaction of a chalcone, trans-4-nitrochalcone reacts with Br2/CHCl3 to produce erythro-2,3-diBromo-3-(4-nitrophenyl)propiophenone. The product...

In the bromination reaction of a chalcone, trans-4-nitrochalcone reacts with Br2/CHCl3 to produce erythro-2,3-diBromo-3-(4-nitrophenyl)propiophenone. The product is a racemic mixture. a) Draw the structure of the enantiomers you form and assign R & S to each of the stereocenters. b) Will you see two spots on a TLC plate for your reaction products? Why or why not? c) Draw the structures of the products that are not formed in the bromination reaction. d) Is this bromination reaction stereoselective? Why or...

For the bromination of trans-cinnamic acid, provide two reasons as to why pyridinium bromide perbromide is the brominating agent of choice as opposed to elemental bromine. Convert 16.5 mmol pyridinium bromide perbromide to grams Convert 300 mmol glacial acetic acid to mL.

Prelab to accompany bromination of trans-cinnamic acid (4 pts each) The stoichiometry of the addition is 1:1, meaning that for every one mole of transcinnamic acid, one mole of Br2 is needed to form the addition product. The Br2 presents as a solution in dichloromethane solvent. This often causes problems for students when calculating stiochiometric equivalents. The bromine solution is 10% Br2 by volume. For instance, 100 mL of solution contains 10 mL of liquid Br2. The density of Br2...
