共价键理论的系统学习

The Systemic Study of Covalent Bond Theory

共价键理论是化学学习中物质结构的重要内容,是价键理论的重要组成部分。非化学专业的学生由于多方面的原因,目前对于共价键理论的学习都只侧重于结论,对于其中的原理比较模糊。尤其是电子轨道方向性的来源,电子波函数最大重叠原理与成键的关系,σ,π成键的描述和杂化轨道的轨道处理问题与分子构型的关系。从原子分子物理的角度对共价键理论系统的学习可以对这些问题进行解释。

Covalent bond theory is the important content of material structure in the chemistry study,meanwhile it is an important part of the valence bond theory.Non chemistry major students study the covalent bond theory only focuse on the conclusion but the principles rather vague due to various reasons.The problems the students encountered in the study process as follows： the source of the electronic track direction, the relationship between the electronic wave function the maximum overlap and the bonding, bonding principles and the hybrid orbital track processing with molecular geometry relationship.In this paper,we can explain the above questions through study the covalent bond theory system from atomic and molecular physics.
