几年来江苏高考题中将有机推断和有机物的合成这两类题型结合在一起考查,且占据较高分值,是重要题型。笔者将从命题特点,解题入手点和解题技巧等方面进行总结,以期帮助学生提高解题效率。一、高考主要命题方向有机推断和合成题的命题者常针对以下知识点命题:1.确定未知物质的结构简式和分子式;2.有机基本反应类型的判断;3.对已知复杂物质化学性质的考查(实质考查官能团名称和性质);4.根据条件书写同分异构体;5.模拟熟悉的有机物和无机物合成指定有机物;
In recent years, the Jiangsu college entrance examination questions will be organic inference and organic synthesis of these two types of questions combined examination, and occupy a higher score, is an important question. The author will summarize the proposition characteristics, problem solving and problem solving skills, etc., in order to help students improve the efficiency of problem solving. First, the main proposition direction of the entrance examination of the main proposition direction Organic synthesis and propositions are often propositions for the following knowledge points proposition: 1. To determine the structure of unknown substances and molecular formula; 2 organic basic reaction type judgments; 3 known complex chemical Nature of the test (substantive test functional groups name and nature); 4 according to the conditions of writing isomers; 5 simulate the familiar organic and inorganic synthesis of designated organic matter;
