键线式结构在有机化学中的教学探讨

Study on the Skeletal Formula Teaching in Organic Chemistry

准确书写化合物的结构是学好大学有机化学的重要组成部分和思想灵魂。键线式是表示分子结构最常用的方法,具有方便、清晰、简明易懂的特点。但课本对这部分的内容鲜有介绍,教学中教师也较少系统地讲解这部分知识点,因此许多学生对键线式的书写规则和运用把握不够准确,容易出现错误。本文对键线式的书写规则和容易出错的地方做简要介绍,并探讨一下将键线式结构融入教学中的几个策略。

Accurately writing the structure of compounds is an important section and soul of learning organic chemistry in college.Skeletal formula is the most commonly used method for representing molecular structure,which is convenient,clear and easy to understand.However,there is rather limited introduction about the content of this part in textbook,and teachers seldom systematically explain the knowledge of this section in teaching.Therefore,many students fail to master the rules and application for writing,then turn to make errors.This paper briefly introduces the writing rules and error-prone points in writing skeletal formula,and provides several strategies for integrating skeletal formula in teaching.
