0.8002 g of (E)-cinnamic acid, 10 mL of glacial acetic acid and 1.7610g of pyridinium tribromide was heated under reflux to demonstrate the bromination of (E)-cinnamic acid. The mass of the final product was 3.4143 g and the melting point range was 175.4-203.4 ℃. What is the theoretical yield, actual yield, percent yield? Please show work! (Pyridinium tribromide and cinnamic reaction react in a 1:1 ratio).

An Alkene addition is being performed. The reactants are .1504 g of trans-cinnamic acid and .3843 g of pyridinium tribromide, these components heated and are reacted within 2 mL of glacial acetic acid to produce 2,3-dibromo-3-phenylpropanoic acid. How much of this final product would theoretically be produced? Would the product be majority threo or erythro?
