Abstract: This article presents a dialogue between Professor K and student Little C, focusing on discussions about several key reactions in alkene chemistry. By incorporating concepts from the periodic table and acid-base theory, the article provides a systematic and comprehensive explanation of alkene reactions. Starting from the fundamental properties of alkenes, it progresses to various typical reactions, including electrophilic addition, halogenation, and hydroboration. The discussion also reflects on designing reactions and the nature of catalysts. Under Professor K’s guidance, Little C gradually deepens his understanding of the mechanisms and principles underlying these reactions. Utilizing the periodic table and acid-base theory, he further enriches his comprehension of organic chemistry.

Key words: Alkene chemistry, Electrophilic addition, Halogenation, Acid-base theory, Hydroboration reaction, Periodic table
