纵观近三年高考模拟题和高考阅卷情况,有机化学基础主要失分点有:(1)概念模糊或相似概念易混淆;(2)化学用语不规范是失分重灾区,如结构式、分子式、结构简式、键线式等混淆,化学键连接错误,书写有机反应方程式漏掉小分子或错写条件等;(3)结构、性质、条件之间转化错位;(4)混淆官能团之间差异性等。归纳
Throughout the past three years college entrance examination simulation questions and the college entrance examination marking situation, the main points of organic chemistry are the points: (1) the concept of ambiguity or similar concepts easily confused; (2) non-standard chemical terms is the loss of weight hit areas, such as structural formula , The structure of simple, key lines and other confusion, chemical bond connection error, writing organic reaction equation omission of small molecules or wrong writing conditions, etc .; (3) the structure, nature and conditions of the shift between dislocation; (4) Sex and so on. induction
