2013年12月,三明市严业安名师工作室成员以《物质结构与性质》为载体,对相似相溶原理、氢键等基本概念与知识进行专题研讨。我们查阅有关参考文献并结合自己的理解,将一些不甚成熟的解答整理如下,供广大中学化学教师在平时备课、研讨时参考。问题1:什么是“相似相溶原理”?解答:“相似相溶原理”是一个关于物质溶解性的经验规律,其内涵是“结构相似的化合物容易互相混溶,结构相差很大的化合物不易互溶”。其
In December 2013, members of Master Yan Yian’an’s workshop in Sanming City carried out a special seminar on the basic concepts and knowledge of similar dissolving principles and hydrogen bonding based on “substance structure and nature”. We refer to the relevant references and their own understanding, some of the less mature answers are arranged as follows, for the majority of high school chemistry teachers in peacetime lesson planning, reference. Question 1: What is the “principle of similar compatibility”? Answer: “Similar principle of compatibility” is a rule of thumb about the substance solubility, its connotation is “Structurally similar compounds easily miscible with each other, the structure of the difference Large compounds are not easy to dissolve. ” its
