高考化学有机推断题综合性强,难度大,情景新,要求高,考查形式主要以填空题为主。此类题常将有机物的组成、结构、性质的考查融为一体,大多以新材料、新药物、新科研成果以及社会热点为题材,综合考查考生的有机知识。解答有机推断题的常用思维方法有:①顺推法:以有机物结构、性质和实验现象为主线,采用正向思维,得出正确结论。②逆推法:以有机物结构、性质和实验现象为主线,采用逆向思维,得出正确推论。③分层推理法:依据题意,分层推理,综合结果,得出正确推论。
The organic chemistry extrapolation problem in the college entrance examination is comprehensive, difficult, new, and demanding. The examination form is mainly based on blank-filling questions. Such questions often combine the examination of the composition, structure, and properties of organic matter. Most of them are based on new materials, new drugs, new scientific research results, and social hot topics. They comprehensively examine the organic knowledge of candidates. The commonly used thinking methods for solving organic inference questions are: 1 The cis-reduction method: taking the organic structure, nature and experimental phenomena as the main line, adopting positive thinking and drawing correct conclusions. 2 Inverse method: Taking the organic structure, properties, and experimental phenomena as the main line and using reverse thinking, the correct inferences are obtained. 3 Stratified reasoning: Based on the meaning of the questions, stratified reasoning, and comprehensive results, a correct conclusion can be drawn.
