有机化合物是高中化学必修的内容之一,也是高考的热点.有机化合物往往有自己的通式、最简式,如果能用“变式法”对物质的分子式进行适当创新变形,从而达到巧解巧算题目的目的.解这类题不仅要求同学们掌握各类物质的化学式、通式、最简式、而且要能发现各类物质内在联系,灵活运用课本知识,结合数学方法锻炼自己的创新变新能力.现结合几例典型题目例析如下,以提高同学们解题速度.一、物质具有相同的最简式或通式,可以通过最
Organic compounds are one of the compulsory parts of high school chemistry, but also the hot spot.Organic compounds often have their own general formula, the most simple, if you can use “variant method ” of the material molecular formula appropriate innovation and deformation, so as to achieve Cleverly solve the purpose of clever calculation problem solving such questions not only require students to master all kinds of chemical substances, general formula, the most simple, but also to find all kinds of internal relations of materials, the use of textbooks knowledge, combined with mathematical methods to exercise their own Innovation and innovation ability.Combination of a few typical examples are as follows, in order to improve the speed of solving problems for students.One, the material with the same most simple or general, through the most
