Abstract:
We developed a computer graphics (CG) teaching material (TM) for university students, concerning
reactions involving drastic changes in the structure of the reactants in the following chlorination, for
example SN1: formation of tert-butyl chloride from tert-butanol and SN2: formation of 1-chlorobutane from
1-butanol. The CG-TM could clearly demonstrate the changes in the structures during the reaction by the
ball-and-stick model, in addition to the image of the energy change in terms of the reaction profile. An
electronic lab-book for chemical experiments in the students’ laboratory at the university was produced,
aiming at the integration of observable-level experiments, symbolic chemical equations, and the molecular
world. The lab-book displays pictures of apparatus, flow-chart of experimental procedures, and reaction
mechanisms with the CG-TM. A preliminary study on the effectiveness of the CG-TM suggested that
students were able to obtain images of SN1 and SN2 reactions.
