Abstract Based on the review characteristics of organic chemistry in senior three, taking the real situation as the carrier, this paper sets questions with different comprehensive complexity, and guides students to predict the material structure and design the transformation route from the perspective of the transformation of functional groups of organic compounds. This paper guides students to understand the reaction process from the perspective of the change of carbon skeleton and chemical bond, and understand the relationship between the type and polarity of covalent bond and organic reaction. The separation and purification scheme is designed by using physical properties, which reflects the integration within the discipline, and enable students to truly establish the basic concept of “composition and structure determine nature”, highlight the problem-solving ideas of organic inference such as comparative analysis and inverse synthesis analysis, develop high-order thinking, promote the improvement of students' key abilities and promote the development of core literacy of chemistry.
