en and edta

Postby Julia Mazzucato 4D » Sat Nov 30, 2019 8:46 pm

Doing practice problems (particularly (9C9 from the TB) and came across the ligands en and edta a few times. What are these, how do we name them, and how would we draw them in a lewis structure?

en = Ethylenediamine (abbreviated as en when a ligand) is C2H4(NH2)2. (first photo shown)

edta= Ethylenediaminetetraacetic acid; C10H16N2O8

en is ethylenediamine or NH2CH2CH2NH2. It is on the chart that Dr. Lavelle gave us for naming coordination compounds.
