探析反应机理与理解反应条件——中英高中化学“烯烃与溴的加成反应”内容比较

Comparison of Addition Reaction of Ethene and Bromine in British A-Level Chemistry and Chinese Chemistry Textbooks

有机化学模块是高中化学的重要组成部分,了解有机化学反应机理有利于从微观角度探析物质的结构与性质。目前国内各版本高中化学教材对烯烃与溴加成反应的描述过于简洁。参考了英国高中化学教材和我国的《基础有机化学》,综合分析不同教材的特点,以期更合理地讲解加成反应过程。

Organic chemistry is an important module in the high school education,which is beneficial for the development of core competencies and values.Understanding the reaction mechanism promotes the ability of substance exploration from a microcosmic view.However,the introduction to the addition reaction of ethene and bromine lacks accuracy in the different editions of current chemistry textbooks.We compared the content of alkene addition in A-Level Chemistry and Fundamental Organic Chemistry,and discussed the characteristics in each version.
