 Bromination Reactions A) Styrene, would also be brominated using the reaction conditions in this experiment. Could it be used instead of trans-cinnamic acid to determine the mechanism of a bromination reaction? Justify your answer.B) Orange color in the product of a chemical reaction comes from trace impurities. Propose a laboratory technique that could be used to remove the impurities and justify your proposal.C) Consider the chemical reaction 2 A + B → C where A has a molar mass of 50.0 g/mol, B has a molar mass of 75.0 g/mol, and C has a molar mass of 125.0 g/mol. What is the theoretical yield for the reaction if 30.0 g of A and 30.0 g of B are reacted together? Show your work. Read 69 times 2 Replies

Show your work.first calculate limiting reagentaccording to balanced reaction2 x 50 g A reacts with 75 g B30 g A reacts with 30 x 75 / 2 x 50 = 22.5 g Bbut we have 30 g B. so B is excess reagentlimiting reagent = Anow2 x 50 g A gives 125 g C30 g A gives 30 x 125 / 2 x 50 = 37.5 g Ctheoretical yield of C = 37.5 g

 Orange color in the product of this reaction comes from impurities that could be separated by column chromatography. Column chromatography could easily separate this orange color and your bromination product.QuoteStyrene, would also be brominated using the reaction conditions in this experiment.
