纵观近几年高考中与有机物的结构相关的题型,发现其共同特征是:通过题给某一有机物的化学式或式量,结合该有机物的性质,对该有机物的结构进行发散性思维和推理,从而考查学生“对微观结构的一定想象力”。因此,必须对有机物的化学式或式量具有一定的结构化处理的本领,才能从根本上提高自身的“空间想象能力”。一、有机物的结构推断的基本规律1.式量相等时的化学式的相互转化关系
Throughout the college entrance examination in recent years and the structure of organic matter related to the type and found that their common characteristics are: Through the title to an organic chemical formula or formula, combined with the nature of the organic matter, the organic structure of the divergent thinking and Reasoning, and thus examine the students “a certain degree of imagination on the microstructure ”. Therefore, it is necessary to have a certain degree of structural treatment of the chemical formula or quantity of organic matter in order to fundamentally improve their “space imagination.” First, the basic rules of the structure of organic matter inference 1.
