摘要:

杂化轨道理论是化学键理论的重要内容,杂化轨道成键能力和杂化轨道之间的夹角是杂化轨道理论教学的重点和难点,多数教材通常直接给出相关公式,忽略导出过程,不能满足部分学生进阶学习的需要。本文给出了相关公式的简易推导,以期解疑释惑,加深学生对杂化轨道理论的认识和理解。

Abstract:

Hybrid orbital theory is an important part of the chemical bond theory. The bonding ability of hybrid orbitals and the angle between two hybrid orbitals are the most important and difficult topics in the teaching and learning of hybrid orbital theory. Most textbooks usually give the relevant formulas directly and ignore their derivation, which does not meet the needs for the advanced learning of some students. This paper provides a simple derivation of these formulas to dispel students' doubts and deepen their understanding of hybrid orbital theory.

Key words: Hybrid orbital theory, Maximum bonding capacity, Angle between two hybrid orbitals
