The chemical reaction starts with 1,2-dichloroethane (ClCH2-CH2Cl) which undergoes dehydrohalogenation to form ethylene (CH2=CH2). Ethylene then reacts with benzene (C6H6) in a substitution reaction to form ethylbenzene (C6H5CH2-CH3). Ethylbenzene is then oxidized to form benzoic acid (C6H5COOH) and finally brominated to form 4-bromobenzoic acid (C6H4BrCOOH).
