The literature value for the melting point range for Trans-9-(2-phenylethenyl)anthracene is 130-133 oC. The obtained range was lower than that at 120.3 to 123.8 oC. Because it is lower than the known value‚ this means the obtain product is not completely pure. Impurities in the compound can result in a decrease in the compounds melting point‚ which is observed here. The impurities could be 1-propanol due to an insufficient drying. If the experiment was performed again‚ the product would need to be

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 determine dibromide’s stereochemical structure‚ and from there determine
