目前发现或人工合成的3000多万种的物质中,大部分是有机化合物,简称为有机物.它们对于人类的健康、丰富人类的物质生活、科学技术的进步和社会经济的发展都有着十分重要的作用.有机化合物的碳原子的结合能力非常强,互相可以结合成碳链或碳环.碳原子数量可以是一、两个,也可以是几千、几万个,许多有机高分子化合物甚至可以有几十万个碳原子.此外,有机化合物中同分异构现象非常普遍,这也是造成有 Most of the more than 30 million substances discovered or synthesized at present are organic compounds, or organic compounds for short, which are of great importance to human health, enrichment of human material life, advances in science and technology, and socio-economic development The organic compounds of the carbon atoms binding ability is very strong, can be combined with each other into a carbon chain or carbocyclic carbon atoms can be one, two, can also be a few thousand, tens of thousands, many organic polymers can even There are hundreds of thousands of carbon atoms.In addition, the phenomenon of isomers in organic compounds is very common, which is also caused by
