摘要
通过对有机化合物和取代反应概念的建构分析,表明甲烷与氯气反应在有机化学教学中有重要的地位。通过理论和实验手段,对日常教学中存在的一些见解,如反应条件（光源的选择）、反应产物种类数、产物的验证方法、反应物的比例、实验危险性等进行了剖析,并提出了甲烷与氯气反应的实验方案。根据教学误区产生的原因,提出了减少和消除教学误区的努力方向。
This paper discussed the construction of the concept of organic compounds and substitution reaction, which showed that the reaction between methane and chlorine played an important role in organic chemistry teaching. Analyzed the misunderstanding of the conditions （such as the selection of light source）, the types of products, the verification method of prod- ucts, the ratio of the reactants and the risks of the experiment of the reaction between methane and chlorine using theoretical and experimental methods, and put forward an improved experi- ment program and the directions to eliminate the misunderstanding of teaching.
