摘要
有机物同分异构体的书写,需要对碳原子和氢原子在有机物结构中的辩证关系有清晰的认识:碳原子和氢原子好比树木的主干和树木的叶子。有机物的同分异构体书写应先有主干碳架,再有枝叶氢原子。复杂有机物的同分异构体的书写,要找不变的结构因素和变化的结构因素,不变的结构因素先写,变化的结构因素后写。
The writing of organic isomers requires a clear understanding of the dialectical relationship between carbon atoms and hydrogen atoms in the structure of organic compounds:carbon atoms and hydrogen atoms are like the trunk and leaves of trees.The writing of isomers of organic compounds should have the main carbon frame first,and then the branch and leaf hydrogen atoms.To write the isomers of complex organic compounds,students need to find the constant structural factors and the changing structural factors.The constant structural factors should be written first,and the changing structural factors should be written later.
