Abstract The third question in the preliminary test of the 35th Chinese Chemistry Olympiad were smartly resolved. From the beginning to the end, with the help of the structural formula, this paper firmly grasped the main line of“how does the old bond break? How does the new bond form?”, which fully demonstrated the evolution process of different reactions to different products. The answers given were also discussed at the same time, and some pieces of teaching advice were provided.
