碳链异构是由于烷烃分子中碳链不同而产生的一种异构现象。它是造成有机物种类繁多的原因之一。碳原子数在4以上的烷烃,都存在着碳链异构体,并且异构体数目随着碳原子数的增加而增加。由于碳链异构的复杂性。长期以来,人们从不同的途径出发,企图找出一个简单易行的书写异构体的方法和计算异构体总数的公式。遗憾的是,这个问题至今未得到圆满解决。人们至今尚未发现碳链所含碳原子数和异构体总数之间存在着直接的函数关系。美国学者 Henze 和 Blair 在此方面作了大量的研究后也指出:甲烷同系列的异构体数目和它们
Isomerization of carbon chains is a heterogeneous phenomenon due to the different carbon chains in alkane molecules. It is one of the causes of the wide variety of organic matter. Alkanes having a carbon number of 4 or more have carbon chain isomers, and the number of isomers increases as the number of carbon atoms increases. Due to the complexity of carbon chain heterogeneity. For a long time, people proceeded from different sources in an attempt to find a simple way to write isomers and to calculate the total number of isomers. Unfortunately, this issue has so far not been satisfactorily resolved. So far, no direct functional relationship between the number of carbon atoms contained in the carbon chain and the total number of isomers has been found. After much research by American scholar Henze and Blair in this area, they also pointed out that the number of methane isomers in the same series and their
