Calculate the theoretical yield of 2,3-dibromo-3-phenylpropanoic acid in 0.7 mmol of trans-cinnamic acid in both mg and mmol.
Calculate the mass of 10.0 mmol of trans-cinnamic acid and the theoretical yield of 2,3-dibromopropanoic acid.
Suppose a student started with 133.0 mg of trans-cinnamic acid, 443 mg of pyridinium tribromide, and 2.60 mL of glacial acetic acid. After the reaction and workup, the student ended up with 0.1683 g of brominated product. Calculate the student\'s theoretical and percent yields.
12. You are given a sample that is believed to be either cis- or trans-cinnamic acid. Would TLC be a good method to determine which compound you have? Why or why not? See structures arom COOH (A) trans-cinnamic acid (B) cis-cinnamic acid

Why is 1,5-hexadiene added at the end of Bromine addition to trans-cinnamic acid? To neutralize any unreacted cinnamic acid molecules To make crosslinking reaction with the double bond of trans-cinnamic acid To make crosslinking reaction with unreacted bromine molecules To neutralize any unreacted bromine molecules To neutralize any molecules of HBr that might be formed as by product
a) Using the line drawings for trans-cinnamic acid and methyl tert butyl ether (MTBE), give the chemical reaction that trans-cinnamic acid gave during extraction (with formal charges included). b) Write out the skeletal structures for the reaction that occurred when the aqueous extract of trans-cinnamic acid was neutralized.
What is the theoretical yield of 1mmol of trans cinnamic acid+1.2 mmols of pyridinium tribromide and what product is made? please note in this reaction acetic acid is added making me believe it is a catalyst.
Bromunation of trans-Cinnamic Acid Show the calculations for the theoretical yield (in grams) of the diromide product). There are 0.017 mol of Cinnamic Acid and 0.020 mol of Pyridinium Tribromide.
What is the stereochemical outcome of reacting trans-cinnamic acid with bromine to form 2,3-dibromopropanoic acid? Please post answer asap thank you! B2 OH Stereochemistry of both bonded bromines?
