Consider this molecule, a hexane with a benzene ring attached to carbon number 2.

考虑这个分子， 一个苯环连接到碳数 2 的己烷。

Sometimes, a hexane can look like a pentane with an ethane sticking off of it.

有时，己烷看起来像戊烷， 上面粘着乙烷。

But pentane, C5H12, has 3 possible isomers and C6H14, known as hexane, has 5.

但是戊烷 C5H12 有 3 种可能的异构体， 而称为己烷的 C6H14 有 5 种。

Ketones, add '-one', so a ketone of a hexane would be hexanone, and amines, you just add '-amine' to the end so methenamine or propanamine.

酮，添加“-one” ，所以己烷的酮就是己酮，而胺，你只需在末尾添加“-胺” ，所以甲胺或丙胺。
