有机反应中,由于参加反应的某些有机物结构特殊,造成该有机物经过反应后,所得有机产物只有一种,那么,这些有机物的结构有什么规律呢?现分别归纳例析如下:一、取代反应规律:若有机物分子中所有烃基氢完全相同,则该有机物中的烃基氢原子被一个其他原子或原子团取代后,只生成一种取代产物.如甲 In the organic reaction, due to the special structure of certain organic substances participating in the reaction, the organic product after the reaction is caused to have only one kind of organic product. Then, what are the regularities of the structure of these organic substances? The following are summarized as follows: 1. Substitution reaction Regularity: If all hydrocarbyl hydrogens in the organic molecule are identical, the hydrocarbyl hydrogen atom in the organic molecule is replaced by one other atom or atom group and only one substitution product is produced.
