Abstract:

Molecular orbital theory is an important chemical bonding theory and also a difficult point in the study of general chemistry. In this article, the problems often encountered by beginners of molecular orbital theory are sorted out and analyzed, and the application of molecular orbital theory is expanded. By tracing the formation and development of the molecular orbital theory, combined with the requirements of the Chemistry Olympiad test questions, summarization and analysis are carried out to deepen the understanding of the molecular orbital theory and promote the teaching of the molecular orbital theory.
