在有机化学诸文献中对同一问题有不同的见解是存在的。教学中遇到这样的问题如何处理呢?个人认为:首先将不同的见解向同学们介绍,然后从如下三方面谈自己的观点及理由。一是文献的时间性;二是实验事实的准确性;三是理论依据的充分性。这样处理效果比较好,下面仅举二例加以说明。 一 简单烷基负离子的稳定性 简单烷基负离子如甲基负离子(CH_3)~-、一级碳负离子(RCH_2)、二级碳负离子 There are different opinions on the same issue in organic chemistry literature. Teaching how to deal with such problems? Personally think: First of all, different views to the students introduced, and then from the following three aspects of their views and reasons. First, the timeliness of the literature; Second, the accuracy of experimental facts; Third, the adequacy of theoretical basis. This treatment effect is better, just give two examples to illustrate. The stability of a simple alkyl anion simple alkyl anion such as methyl anion (CH_3) ~ -, a carbon anion (RCH_2), two carbon anion
