在烃及其衍生物的复习过程中应注意以下几个方面: 一、狠抓物质结构,弄清各类有机物的概念和特性 1.要从碳键、官能团等结构上分清各类物质的异同。如苯的同系物是指组成为CnH_(2n-6)的烷基苯,而苯乙烯、萘等其它芳香烃均不属之;酚是指羟基(—OH)直接与苯基相连的一类有机物,而醇是羟基与键烃基相连的有机物。
During the review of hydrocarbons and their derivatives, attention should be paid to the following aspects: First, pay close attention to the structure of the material and clarify the concepts and characteristics of various types of organic materials. 1. Distinguish differences and similarities of various substances from carbon bonds, functional groups, and other structures. . For example, a benzene homologue refers to an alkylbenzene having a composition of CnH_(2n-6), and other aromatic hydrocarbons such as styrene and naphthalene do not belong to the same; phenol refers to a group in which a hydroxyl group (—OH) directly associates with a phenyl group. Organic matter, while alcohol is an organic compound in which the hydroxyl group is bonded to a bond hydrocarbon group.
