To predict whether the reaction of trans cinnamic acid is stereoselective in nature or not. The reaction of trans cinnamic acid with dibromine is an example of the reaction of an alkene with dibromine. A stereoselective reaction is a reaction in which the possibility of the formation of two or more than two products is there. Since here the addition of bromine to trans cinnamic acid is leading to the formation of more than one product, hence the reaction is stereoselective in nature. The melting point of the product formed in the given reaction is found to be around 176.3°C - 180.6°C which is close to the product formed if the bromination had followed anti addition. Hence it can be said that the reaction of trans cinnamic acid with Dibromine follows involved anti addition.
