Abstract:

Organic chemistry is an important basic course for chemistry and related majors, but many reactions, esoteric mechanisms and complex synthesis make it one of the most difficult courses in science and engineering colleges. In the teaching of organic chemistry, we use the comparative teaching method to explain the knowledge that is easy to be confused and difficult to understand and remember. Through concept comparison, structure and property comparison, reaction condition comparison, mechanism comparison, synthesis method and other multi angle analysis and comparison, we can grasp the main contradictions of things, help students clarify the similarities and differences of knowledge, stimulate students' interest in learning, and improve the quality of teaching.

Key words: Organic chemistry, Contrast method, Classroom teaching
