As the semester comes to a close, sophomore chemistry and biochemistry majors completed their last experiment in Organic Chemistry Lab. The students tested the rates of different substitution reactions (shown in the pictures above). Many different experiments were performed during the semester; however, when asked to reflect on these experiments, students agreed that their three favorites were analyzing over the counter drugs using thin-layer chromatography, identifying compounds by infrared spectroscopy, and synthesizing Dulcin, an artificial sweetner.
