有机氧化还原反应方程式的配平,对于研究和定量计算有机反应是很重要的。但由于有机氧化还原反应比无机反应更为复杂,因此,用直观或氧化数法直接配平整个反应方程式就更加困难。本文介绍一种利用氧化还原反应中相互联系、不可分割的氧化与还原两个半反应,以配平有机氧化还原反应方程式的方法。这种所谓的半反应法比较简便,又易于掌握。为了理解和掌握半反应法,首先应当弄清有机化学中的氧化还原概念。在有机化学中,氧化反应一般是指有机物脱氢或得氧的过程,而还原反应是指加氢或失氧的过程。因此,烃转变为醇、醇转变为醛、醛转变为酸是氧化反应,其逆过程是还原反应;而烷转变为烯、烯转变为炔是氧化反应,其逆过程是还原反应: Balancing the organic redox reaction equation is important for studying and quantifying organic reactions. However, since organic redox reactions are more complicated than inorganic ones, it is more difficult to directly scale the entire reaction equation using either visual or oxidation number methods. This article describes a redox reaction using interconnected, indivisible two half-oxidation and reduction reaction to balance the organic redox reaction equation. This so-called half-reaction method is simple and easy to grasp. In order to understand and master the half-reaction method, we should first understand the concept of redox in organic chemistry. In organic chemistry, the oxidation reaction generally refers to the organic dehydrogenation or oxygen process, and the reduction reaction refers to the process of hydrogenation or oxygen. Therefore, the conversion of hydrocarbons into alcohols, alcohols into aldehydes, aldehydes into acids is the oxidation reaction, the reverse process is a reduction reaction; and alkane into alkenes, alkenes into alkyne is the oxidation reaction, the reverse process is a reduction reaction:
