7th edition 9C.5

Postby Karina Koo 2H » Sat Dec 08, 2018 5:06 pm

is HN(CH2CH2NH2)2 polydentate and why? If so, what is the maximum amount of places this ligand can bind simultaneously to a metal ion?

Yes, HN(CH2CH2NH2) is tridentate. It's easier to see when looking at the structure drawn out, but there are 3 N atoms each with a set of lone pairs that are ready to form a coordinate covalent bond. The ligand bends in such a way to where the N atoms are able to bind to the same metal atom.
