卤代烃的系统命名问题辨析

本文对有机化学中文教材中卤代烃系统命名法常见的错误进行了分析,通过对比中国化学会制定的80原则中有机物系统命名原则,确定了正确的命名方法：应该选择最长的碳链为主链并作为母体名称;应该遵循最低系列原则为取代基编号;化合物名称中烷基应该排列在卤原子之前。

Comment on System Nomenclature of Halohydrocarbon

The mistake of halohydrocarbon＇s system nomenclature in Chinese organic chemistry text book was summarized and discussed. According to 80 principle published by China Chemistry Society, the correct method was obtained.. The longest continuous chain of carbon atoms in the formula was identified as the parent chain and named with parent title, Identify the side-chains and number them, and the direction being so chosen as to give the lowest numbers possible to the side chains and this principle is applied irre- spective of the nature of the substituents halogen The arrangements of side-chain and halogen in name was followed stereochemistry sequence principle and alkyl was preferential than halogen.
