Abstract At present, organic chemistry teaching in senior high school is faced with a wide range of functional groups, focusing on mechanical memory, splitting functional groups into many isolated categories without constructing theoretical analysis models and reaction law systems. Through the analysis of the new curriculum standard, taking bromoethane substitution and elimination reactions as examples, students are guided to quantitatively analyze electronegativity data, qualitatively infer inductive effect, speculate on reaction active site, and predict reaction process and mechanism. Therefore, an understanding perspective of organic chemical reaction analysis based on the principle elements of inductive effect is established, and the analysis system and model of organic chemistry are constructed to grasp the essence and law of organic reaction. Cultivate students’ ability to understand and reflect from macro and static perspectives to micro and dynamic analysis of principles, develop core competencies, and establish a unity of opposites such as positive and negative, yin and yang, and universality and particularity.
