What is the stereochemical outcome of reacting trans-cinnamic acid with bromine to form 2,3-dibromopropanoic acid? Please...
a. Based on the stereochemistry of the addition of bromine to trans-cinnamic acid, write the structure of the product(s) that will form when bromine reacts with (Z)-2-hexene.
Draw the mechanism of the bromination reaction between trans cinnamic acid and bromine. Be sure to include stereochemistry( wedge and dashed structures). The product obtained was the racemic mixture of (2R,3S) and (2S,3R) of 2,3-dibromo-3-phenylpropanoic acid.
2. Draw the entire mechanism for the syn- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers.
3. Draw the entire mechanism for the anti- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers.
3. Draw the entire mechanism for the anti- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers. *Use backside of paper.
Calculate the theoretical yield of 2,3-dibromo-3-phenylpropanoic acid in 0.7 mmol of trans-cinnamic acid in both mg and mmol.
another answer is the amount of trans cinnamoc acid was insuficient Reaction progress of bromine addition to trans-cinnamic acid can be monitored by testing samples from reaction mixture over specific periods of times with TLC plates as shown by the attached picture. How can you explain your results if you only obtained spot (b) at the end of reaction? a) b) c) a) cinnamic acid b) cinnamic acid and product c) Product the applied eluent in the TLC test was...

You attempt to perform a bromination of trans-cinnamic acid in the hopes of producing the product shown below. You decide to take a 1H NMR spectrum of what you hope is the product. Signals with which of the following approximate chemical shifts would indicate that the product did not form? The listed regions would not be useful in determing reaction success. ~ 12.0 ppm ~ 5.5 ppm ~7.0 ppm Br O OH Br
