同分异构体书写是中学化学教学中的重点,也是高考必考的一个热点.研究教材会发现:教材中只有在烷烃和苯的同系物两处讲到同分异构体的书写,且内容简单.相应知识在高考大纲中的要求为:理解基团、官能团、同分异构体、同系物等概念.能够识别结构式(结构简式)中各种原子的连接次序和方式、基团和官能团.能够辩认同系物和列举异构体.近几年高考化学试题中对同分异构体的考查更是乐此不疲,不过在考查时
Isomers of writing is the focus of chemistry teaching in secondary schools, but also a hot college entrance exam will be studied textbooks will find: textbooks only in alkanes and benzene homologues about the isomers of the two written, and Content is simple.The corresponding knowledge in college entrance examination outline requirements: understanding groups, functional groups, isomers, homologues and other concepts.Can identify the structure (structure) in the order and manner of connection of various atoms, the group And functional groups. To identify homologues and enumeration isomers. In recent years, college entrance exam chemistry isomers on the examination is even more bored, but when examining
