一、问题的提出《中学化学教学参考》2013年第8期刊发了王燕、魏崇启两位老师“苯的溴化反应实验创新设计”一文。笔者对两位作者实验设计的新颖性、实验装置的简洁性、实验操作的方便性表示赞同,但是对该实验设计原理的科学性、实验操作的可行性表示怀疑。按照两位作者的设计(见图1)~([1]),笔者重新做了该实验,在实验过程中出现了许多意想不到的现象。为了究其原因,笔者查阅了大量参考资料后,对两位作者的实验创
First, the problem raised “High School Chemistry Teaching Reference” 2013 the eighth issue of Wang Yan, Wei Chongqi two teachers “bromination reaction of benzene experimental design ”. The author agrees with the novelty of experimental design, the conciseness of experimental apparatus and the convenience of experimental operation. However, the author doubts the scientific nature of the experimental design principle and the feasibility of experimental operation. According to the design of the two authors (see Figure 1) ~ ([1]), the author did the experiment again, and many unexpected phenomena appeared during the experiment. In order to study the reason, after I consulted a large amount of reference materials, I made an experiment on two authors
