Charge of ligands

Postby NabilaNizam-1K » Fri Jun 08, 2018 1:27 pm

Since there is a large number of ligands that form coordination compounds with metallic atoms, do we have to memorize the charges of these ligands or is it more beneficial to determine the charge using Lewis structure?

I find using the Lewis structures helpful especially when calculating the coordination complex number and the oxidation number

There are some ligands that are common polyatomic ions, like oxalate (C2O4)2-. Some of the textbook problems use these repeatedly, so memorizing some ions could save time.

Yes I think it would be helpful to know the charges to save time and I think you should know the common ones.

What are the common ones?

will we lose credit by just having them memorized and not writing out how we came to the answer?
