摘　　要：有机化学中的SN2,SN1,E2,E1反应在学习中有着重要的作用,同时也是学习中易混淆的知识点.通过总结它们的反应机理、反应影响因素和反应相互竞争关系图,并利用竞争关系图解答了一些典型考研真题,方便读者理解和掌握SN2,SN1,E2,E1反应的相互竞争关系.The SN2, SN1, E2 and E1 reactions play an important role in learning organic chemistry, which are also confusing concepts for learners. Their reaction mechanisms, influencing factors and competitive relationship diagrams are summarized in this article. Subsequently, some typical questions of postgraduate entrance exams are solved successfully with the competitive relationship diagrams. Therefore, it will help readers to understand and grasp the competitive relationships of SN2, SN1, E2 and E1 reactions.
