Hi,
I have learned that pi-donor are those ligands which donate their pi electrons to metal centre while pi-acceptor accepts electron from filled d(pi) orbital to their pi* orbital.
Now, I'm confused, why oxygen, having two pi* electrons cannot act as a pi-donor while NO, having one pi* electron only can?
Thank you!
