有机化学中箭头的使用

Applications of Arrow Symbols in Organic Chemistry

在有机化学中，箭头符号是反映反应的本质及反应物和产物之间关系的。对有机化学中经常使用的箭头符号进行分类、解释和讨论，明确各类箭头符号的含义和适用范围，分析和解决了学生在使用箭头符号过程中易于误用的问题，同时介绍了反应机理中显示共价键发生异裂后电子对归属的新型变形弯箭头的使用。

Arrow symbols represent the nature of reactions and the relattonship ot me react- ants and products in organic chemistry. This paper expounded the classifications, explanations and discussions of the arrow symbols widely used in the teaching and learning of organic chemis- try, and clarified their meaning and ranges of application. In addition, this paper analyzed and addressed the common misuse of the arrow symbols, and introduced the new bouncing curved ar- row for explaining mechanisms of reactions that bouncing curved arrows more explicitly describe bond formation in reactions with the possibility of different regioisomeric products.
