Together we'll explore those organic chemistry labs we love oh so very much.

One is the result of a syn addition, the other is the result of an anti addition mode. Bromination of Trans-Cinnamic Acid The Importance of Bromination Although most practical applications of chemistry do not include brominated products, the reaction is important in research and industry.

authentic trans-cinnamic acid to redo the lab. (You will receive a minor point deduction if you (You will receive a minor point deduction if you take authentic sample, but it is better to do so than to not get the rest of the lab done.).
Objective: To be able to conduct a reflux reaction, and practice improving recrystallization and mp determination, by the bromination of trans-cinnamic acid to form 2,3-dibromophenylpropanoic acid, and connect syn and anti addition concepts and stereochemical consequences (erythro & threo) from the addition mechanism.
Bromination of trans-cinnamic acid resulted in the formation of 2,3-dibromophenylpropanoic acid, C 9 H 8 Br 2 O 2. Crystallization from ethanol–water () gave crystals of different shapes.
