Bromination of trans-cinnamic acid

Abstract The bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid, the product was identified by its melting point and infrared spectrum resulting in erythro-2,3-Dibromo-3-phenylpropanoic acid after comparing similar properties. Introduction In this lab, the bromination of trans-cinnamic acid was completed to…
