高考试题中有机化学试题覆盖的知识相对集中而稳定,涉及的主要知识考点有:1.有机物的命名与分类;2.同分异构体;3.有机化学反应;4.高分子化合物;5.有机物的推断;6.有机综合题。以推断型试题为主,且多以信息迁移题的形式出现。这些题在“扣纲守本”原则的指导下,重在考查学生对有机化学基本原理掌握的熟练程度以及逻辑思维能力,接收信息的自学能力和知识迁移能力。一、抓物质结构,弄清各类有机物的概念及其特性1.从结构上分清各类有机物的异同例如,苯的同系物是指符合通式C_nH_(2n-6)(n≥6)的芳香烃,其结构特点是:①分子中只含一个苯环,②仅由
Knowledge of the topics covered by the organic chemistry test in the college entrance examination is relatively concentrated and stable. The main knowledge involved are: 1. Nomenclature and classification of organic substances; 2. Isomers; 3. Organic chemical reactions; 4. Macromolecular compounds; 5 Organic matter inference; 6 organic synthesis. Inference type test-based, and more information migration problems in the form of. Guided by the principle of “keeping the status quo and keeping the status quo,” these questions focus on examining students’ proficiency in mastery of the basic principles of organic chemistry as well as logical thinking ability, self-learning ability of receiving information, and knowledge transfer ability. First, grasping the structure of the substance, to understand the concept of various types of organic matter and its characteristics 1. From the structure of the similarities and differences of all kinds of organic matter For example, the benzene homologue refers to the general formula C_nH_ (2n-6) (n ≥ 6) Aromatic hydrocarbons, the structural features are: ① molecule contains only a benzene ring, ② only by
