有机化学是中学化学中非常重要的内容,其知识系统庞大,不好记忆,为便于同学们理解掌握,笔者把一些常用的有机物知识进行归类,供同学们参考.一、有机物的空间结构1.四类平面结构2·丁基同分异构体的四类应用一氯丁烷的同类同分异构体、一丁醇的同类同分异构体、戊醛的同类同分异 Organic chemistry is a very important part of middle school chemistry. Its knowledge system is huge and it is not well-memorized. In order to make it easier for students to understand and master, the author classifies some commonly used organic knowledge for classmates’ reference. I. Spatial structure of organic matter 1 The four types of four-type planar structure of 2 · butyl isomers in the four types of applications of the same isomer of chlorobutane, the isomeric form of 1-butanol, the same type of valeraldehyde
