有机化合物知识层次是:由烃到烃的衍生物;由烃的单官能团的衍生物到多官能团的衍生物;由有机小分子化合物到有机高分子化合物。复习时,应着重注意以下几方面:一、根据结构讲清基本概念,掌握命名方法。如同系物和同分异构体、同素异性体,同位素;—OH和OHˉ;—NO_2和NO_2和NO_2、NO_(2-);—NH_2和NH_3、NH_(4+);—SO_3H和HSO_(3-)等,找出它们的区别。对有机物的命名,,抓住结构特点,找出主链及取代基和官能团分别进行定位,加以命名。还要注意部分有机物的俗名。同时又要学会不问原子团间组合成不同的有机物。
The level of organic compound knowledge is: derivatives from hydrocarbons to hydrocarbons; monofunctional derivatives of hydrocarbons to multi-functional derivatives; organic small molecule compounds to organic polymer compounds. When reviewing, you should pay attention to the following aspects: First, according to the structure to clarify the basic concepts, master naming methods. Like the isomers and isomers, allotropes, isotopes; —OH and OHˉ; —NO 2 and NO 2 and NO 2 , NO —(2-); —NH 2 and NH — 3, NH —(4+);—SO — 3H and HSO (3-) and so on, find out their difference. For the nomenclature of organic matter, grasp the structural characteristics, find out the main chain and the substituent and the functional group respectively to locate and name it. Also pay attention to the common name of some organic materials. At the same time, we must learn not to ask whether the atomic groups combine into different organic matter.
