Toluene was utilized in both EAS reactions—bromination and nitration—in order to synthesize bromotoluene and nitrotoluene isomers. Although these reactions are different, they could turn into the exact same molecule through synthesis, which is then evaluated for which underwent a more green reaction. Green chemistry reactions utilize compounds that are not toxic to the environment and are more cost efficient, while non-green chemistry uses compounds that are hazardous to the environment—known as principle 4. Both reactions were analyzed, through atom economy and cost and waste calculations, purity, and PMI, to determine which reaction was more green. The products were verified through FTIR and 1H NMR spectroscopies. PMI is the ratio between
