在基础有机化学教学中,常需借助模型来讲解有机化合物分子的立体形象和有机反应过程中的立体化学特征。为了配合环己烷的构象、饱和碳原子上的亲核取代反应以及其它有机化学反应的立体化学特征的教学,我们自制了两种简易模型,通过几年来课堂演示的实践,证明其效果较好。现将这两种模型的制作和使用方法简介如下。 In the teaching of basic organic chemistry, it is often necessary to use the model to explain the stereoscopic image of the organic compound molecule and the stereochemical characteristics during the organic reaction. In order to match the conformation of cyclohexane, the nucleophilic substitution reaction on saturated carbon atoms and the stereochemical teaching of other organic chemical reactions, we have made two simple models by ourselves and proved their effectiveness through several years of classroom demonstrations . The two models are now produced and used as follows.
