价层电子对互斥理论本是一个十分简单的理论,判断或预测分子、离子立体构型时应用它可快速方便地解决问题,多数同学觉得学懂容易。但具体应用时不少同学喜欢套用课本上的计算中心原子的孤电子对数公式,这样在实际应用时费时低效,且时间稍长,就忘了公式,不知所措。其实,在应用时大可不 The valence electron-mutex theory is a very simple theory. Judging or predicting molecules and ion-stereoconfiguration can solve problems quickly and conveniently. Most of the students think it is easy to learn. However, many students prefer to apply the solitary electron logarithm of the calculation center atom in the textbooks. In this way, it is time-consuming and inefficient in actual application. For a long time, the formula is forgotten. In fact, in the application of choice
