关于烃的分子式的推断,课本上只介绍了利用相对分子质量和元素的百分含量进行计算,使用面小,局限性很大.下面谈谈推断烃的分子式常用的几种方法.
With respect to the inference of the molecular formula of hydrocarbons, textbooks only describe the use of the relative molecular mass and the percentage content of elements for calculation. The use of a small surface is quite limited. Here are some of the commonly used methods for inferring the molecular formula of hydrocarbons.
