Use of Tablet in College Chemistry Experiment - An approach to developing an electronic textbook

摘要

We are developing an electronic textbook for a basic chemistry-experiment for university students in which reaction mechanisms are shown by Computer Graphics (CG). The CG of chemical reaction was made based on empirical molecular orbital calculations. The CG included following reactions as a model of Walden's inversion where drastic change in structure takes place; hydroxylation of methyl chloride, formation of 2-butyl alcohol and 1-butyl bromide. The CG can simultaneously demonstrate the nature of the reaction such as structural change by the space-filling and ball-and-stick models in addition to providing an image of energy change by the reaction profile. The electronic textbook also displays pictures of apparatus and flow-charts of small-scale experiments. Therefore, students are able to conduct experiments smoothly and safely while studying dynamical reaction mechanism shown by the CG. The electronic textbook on a tablet could be used to integrate the experimental observable level and the molecular world.
