Abstract: Structural chemistry provides students with an essential framework for understanding molecular electronic structures, spatial configurations, and the fundamental nature of chemical reactions at the microscopic level. This study employs GaussView software to conduct dynamic visual analyses of atomic and molecular orbital symmetry, electron configurations, and energy characteristics. The methodology enables thorough investigation of the molecular orbital symmetry conservation principle. These pedagogical strategies not only successfully reduce the cognitive barriers posed by abstract concepts but also substantially enrich course content while demonstrating notable improvements in instructional effectiveness.
