有机物种类繁多,同类物质有相似的组成 和结构,且它们具有相同的通式．如果我们掌握 了它们的通式,对研究和解决这类物质的有关 问题就会带来诸多的方便．下面就介绍各类有 机物通式的导出方法及应用． 一、结构导出法:结构导出法就是根据有机 物中几种常见元素最多的成键数(如碳元素可 成四键、氢只能成一键、氧可成两键、氮可成三 There are many kinds of organic substances, similar compositions and structures of similar substances, and they have the same general formula. If we grasp their general formulae, they will bring a lot of convenience to researching and solving problems related to such substances. The following describes the export method and application of various types of organic matter. First, the structure derivation method: The structure derivation method is based on the number of bonds that are common to several common elements in organic matter (for example, carbon can form four bonds, hydrogen can only form one bond, oxygen can form two bonds, and nitrogen can become three.
