求算有机物的分子式,是学习有机化学的重要基础知识和基本技能。求有机物分子式的途径有很多,总体来讲,首先要判断有机物中所含元素的种类,然后依据题目所给的条件确定有机物分子中各元素的原子数目,从而确定有机物的分子式。下面笔者根据多年的教学就有机物分子式的求解总结出几种常用的方法。 Calculating the molecular formula of organic matter, is an important basic knowledge and basic skills to learn organic chemistry. There are many ways to find the molecular formula of organic matter. Generally speaking, we must first determine the kinds of elements contained in the organic matter and then determine the atomic number of each element in the organic molecule according to the conditions given in the title to determine the molecular formula of organic matter. Following the author based on years of teaching organic molecules formula to sum up several commonly used methods.
