Abstract. The overarching goal of our ongoing guided inquiry project is to develop a range of green Nobellaureate-type experiments that can be used in several undergraduate science lab courses. Nobel green chemistry reactions are beneficial to mankind because they are environmentally friendly and also reduce the waste disposal costs. Our project was guided by a specific chemistry research question, i.e., in the Diels-Alder reactions between maleic anhydride and dienes (e.g., furan, pyrrole, and thiophene), which experimental conditions produce the most crystalline monomers? Maleic anhydride, furan, 2-methyl furan, pyrrole, thiopene, and solvent (tetrahydrofuran or o-xylene) were mixed, refluxed and then left to stand for one week at room temperature. The crystalline products were analyzed by various techniques including melting point, thin-layer chromatography (TLC), high performance liquid chromatography (HPLC), Infrared (IR) spectroscopy, and Nuclear Magnetic Resonance (NMR) spectroscopy.
