Abstract:
In the substitution and elimination reactions of haloalkanes, the attacking reagents are all negatively charged entities or multi-electron groups, so the competition reaction between substitution and elimination of haloalkanes is the key and difficult part of the teaching content. This article introduces the organization and design of this part of teaching contents, so that students can better understand and grasp this part including the influence of reaction substrates, attacking reagents and reaction conditions on dominant reactions and products. The instructional design plays an important role in training students' ability of analysis, thinking and flexible application of knowledge.
