很多学生在做有机推断题时,经常会因为找不到解题的突破口而一筹莫展,其实有些题目的突破口很容易找到,就是一些常见的反应条件和常见有机物的性质,以及题给的信息,下面我就从这三个方面来谈谈自己的一些体会.一、利用反应条件作为突破口1.设计表格:将常见的反应条件和对应反应列举出来,让学生通过回忆填写正确的对应序号.
Many students do organic inference problems, often because they can not find a breakthrough in the problem and do nothing, in fact, some problems can easily find a breakthrough, is some of the common reaction conditions and the nature of common organic matter, as well as the information given, the following I will talk about some of my own experience from these three aspects. First, the use of reaction conditions as a breakthrough 1. Design the table: the reaction conditions and the reaction of the common cited out, so that students fill in the correct memory through the corresponding serial number.
