烃不但是有机化学的基础内容、考查的重点知识,同时也是逐渐渗透有机化学学法及培养各种能力的载体,因而学习烃时应重点掌握甲烷、乙烯、乙炔及苯四种典型物质的结构特点与性质,灵活拓展知识宽度,运用迁移应用方法,就较易突破烃的难点内容。 Hydrocarbons are not only the basic contents of organic chemistry, but also the key knowledge of the test. At the same time, they are also carriers for gradually penetrating organic chemistry and cultivating various abilities. Therefore, the study of hydrocarbons should focus on the structures of four typical substances of methane, ethylene, acetylene and benzene Characteristics and nature of the flexibility to expand the breadth of knowledge, the use of migration applications, it is easier to break the difficult content of hydrocarbons.
