Textbook Question 9C:5

Postby SLai_1I » Fri Dec 04, 2020 7:35 pm

I was going through the textbook problems for the coordination compounds section and had trouble with problems 5b. and 5d. How can CO3 2- sometimes be bidentate, and how is oxalate bidentate? Please help if you can!

When you draw out the lewis structure of CO3 2- you can see that there are two lewis structures. One structure has one CO double bond and two single CO bond. In this structure the Oxygen is capable of interacting with a transitional metal at two different places so it is classified as bidentate. The other structure has two CO double bond and one single CO bond that is capable of interacting with TM so it is classified as just monodentate(not sure what it is called).

To figure out if a ligand is polydentate, look at the molecular structure and look if there are atoms like carbon between the donor atoms. Spacing is the key factor.
