Question

What is the coordination number of Fe in the compound [Fe(EDTA)]^-1

Answer 1

Hi Dude

First let me tell you about EDTA

it stands for ethylene diammine tetraactate ion.

It has 4 Carbon as attacking atom and two nitrogen sometimes.

So it is hexadentate ligand also called flexidentate ligand.

In the Above question there two answers either 4 or 6 here the answer would be 6 because if you check the oxidation number it comes out to be +3 which is correct

Hope answers the question
