Abstract: This paper conducts an in-depth analysis of the organic chemistry question (Question 9) from the 38th China Chemistry Olympiad (Preliminary), which primarily examines aromatic electrophilic substitution reactions. Focusing on the application of electronic effects, directing effects, and mechanisms of electrophilic substitution reactions in problem-solving, the study aims to provide valuable references for chemical competition training and enhance comprehensive understanding of aromatic electrophilic substitution reaction mechanisms.
