有机合成与有机推断是高考的热点,是命题者的保留题目,预测今后将继续成为有机部分化学试题的主要考点,并且很可能逐步向综合性、信息化、能力型方向发展。而如何解有机合成与有机推断题是教学的重点内容之一,也是备考师生关注的重点内容之一。一、有机合成与有机推断题的特点 1.命题形式上多以框图的形式给出烃及烃的衍生物的相互转化关系,考查反应方程式的书写、判断反应类型、分析各物质的结构特点和所含宫能团、判断和书写同分异构体等;或者是给出一些新知识和信息,即信息给予试题,让学生现场学
Organic synthesis and organic inference are the hot spots in the college entrance examination and are the reserved topics for the proponents. It is predicted that the future will continue to be the main test point for the organic part chemistry questions, and is likely to gradually develop into a comprehensive, informative and capable type. How to solve organic synthesis and organic inference questions is one of the key elements of teaching, but also one of the key content for the pro forma students and students. First, the characteristics of organic synthesis and organic inference questions 1 Propositional form and more in the form of a block diagram of hydrocarbon and hydrocarbon derivatives mutual conversion relationship, to examine the reaction equation writing, to determine the reaction type, analysis of the structural characteristics of the material and Including palace can group, judgment and writing isomers, etc .; or is given some new knowledge and information, that is, information given to test questions, let the students live
