有机反应类型是联系有机化合物的一条纽带,是高考的热点。有机化学反应的主要类型有:取代、加成、消去、氧化、还原、加聚、缩聚和裂化反应等。其中取代反应包含卤代、硝化、磺化、酯化、水解、醇分子间的脱水反应等。复习有机反应类型时,要在理解概念的基础上,多角度、多方位地把握它们,才能够灵活运用。一、从概念上准确把握各类有机反应的特点1.取代反应:有机物分子中的某些
Organic reaction type is a link to organic compounds, is a hot college entrance examination. The main types of organic chemical reactions are: substitution, addition, elimination, oxidation, reduction, polyaddition, polycondensation and cracking reactions. The substitution reaction includes halogenation, nitration, sulfonation, esterification, hydrolysis, dehydration reaction between alcohol molecules and the like. When reviewing the types of organic reactions, it is necessary to grasp them in a multi-perspective and multi-directional manner based on the concept of understanding so that they can be used flexibly. First, from the concept of accurate grasp of the characteristics of various types of organic reactions 1. Substitution reaction: Some organic molecules
