How do you find the oxidation state of the compound [Pt(H2NCH2CH2NH2)2 Cl2]?

I think you are asking about the oxidation state of the metal cation in the coordinate compound. The overall charge of this compound is 0 or neutral, so we know that whatever charges each of the species inside the coordination sphere contains cancels out overall. We have Pt coordinated to four ligands here: 2 ethylenediamine molecules and 2 chloride ions. En is neutral while each chloride has a charge of -1, for a charge of -2 for both of them. The whole compound is neutral so we know the charge of the Pt must cancel out the charges of the Chlorides. Thus, Pt must have a charge of +2, meaning it has an oxidation state of (II) in this molecule
