原子轨道杂化理论是高中化学的难点内容,本人在此罗列了几个在教学过程中学生容易出现的疑点问题,希望能对学生学习和复习本节内容起到抛砖引玉的作用。一、为什么有些分子或离子的中心原子成键时其原子轨道必须先杂化?原子轨道杂化的目的更多地是为了解决共价键的方向性及同种共价键的等性问题。以CH4分子为例:中心原子碳的价电子为
The atomic orbital hybridization theory is a difficult part of high school chemistry. Here I list a few questions that students are prone to appear in the process of teaching. I hope I can help students learn and review the contents of this section. First, why some molecules or ion centers when the atom atoms orbitals must first hybridization? The purpose of atomic orbital hybridization is more to solve the covalent bond orientation and the same kind of covalent bond isotropy. Taking CH4 as an example: The valence electron of central atom carbon is
