Diethylenetriamine

Postby KDang_1D » Sat Nov 23, 2019 9:05 am

In "diethylenetriamine," why does ethylene come before amine? Not A before E as would be for alphabetical order? In the other example "pentaamminechlorocobalt(II) chloride hydriate," "ammine" comes before "chloro" regardless of the prefix.

*Also is NH3 spelled "amine" or "ammine" because apparently these two compounds spell it differently (according to my notes and google)

Ethylene comes before the ammine because the ligand goes before the ion in naming.

Also, I think the difference between "ammine" and "amine" is that "ammine" is used when ammonia is acting as a ligand while "amine" is used when the compound formed ammonia by replacing hydrogen atoms with other hydrocarbons.
