摘　　要：有机反应按成键方式可以分为自由基反应、离子型反应和协同反应，基础有机化学中涉及的大部分反应属于离子型反应。掌握反应物的电性结构，清楚反应物中的亲核部位和亲电部位，不仅有助于学生理解离子型反应历程，轻松记忆反应，而且有助于学生举一反三，触类旁通，推导出课本中未曾讲述的反应。According to the bonding styles, organic reactions are classified into three types： free radical reactions, ionic reactions and synergy reactions, and most of the reactions discussed in fundamental organic chemistry belong to ionic reactions. If the charge distribution especially at the nucleophilic sites and the electrical sites in the reactants were appreciated, it would not only help students understand the mechanisms and memorize the reactions discussed in the textbook, but also help to deduce the reactions not discussed before.

关 键 词：离子型反应 电性结构 亲核试剂 亲电试剂
