摘　　要：共振论是有机化学三大结构理论之一,对描述客观存在的π电子离域的π-π共轭体系、P-π共轭体系结构很有用,更重要的是在表达电子离域的分子结构式书写上有其独到之处,但是学生在理解和应用共振论解释结构和化学反应时,和杂化轨道理论和分子轨道理论区分不清,同时,学生对共轭分子结构极限式的书写也是存在写不全的问题。为了教会学生如何很好地掌握三大结构理论并能熟练应用,为此对共振论重点阐述的同时,也将其与杂化轨道理论和分子轨道理论进行对比学习。Resonance theory is one of the three structure theory of organic chemistry,it is useful to describe the electron delocalization of ＂π - π and P- π conjugate system,it has its unique on the molecular structural formula writing of electron delocalization,but students are not distinguish in the interpretation and application of resonance theory of structures and chemical reaction,and the hybrid orbital theory and molecular orbital theory,as well as the conjugate molecular structure is also full of problems in writing.In order to teach the students how to well grasp three structure theory and proficient in application,therefore,the contrast study of resonance theory and hybrid orbital theory and molecular orbital theory was carried on.
