Answer #1

Na2(IrCl6)

Let us consider the x to be the oxidation state of the central metal atom. Ir is the central metal atom. Here the oxidation state of Na is +1. Charge of Cl is -1.

Now, x + 6x(-1) = 2 =>x = +4

Fe(acac)3: Let x is the oxidation state of Fe and the charge of acac is -1.

x + 3 x (-1) = 0 => x = +3

RhCl(PPh3)3 : Let x is the oxidation state of Rh and the charge of Cl is -1 and PPh3 is 0.

x + (-1) + 0 = 0 => x = +1

Ba[Re(H)9]: Let x is the oxidation state of Re and the charge of H is -1 and the oxidation state of Ba is +2.

x + 9 x (-1) = -2 => x = +7

Mo(CO)6: Let x is the oxidation state of Mo; charge of CO is 0

x + 0 = 0 => x = 0

If the reaction of Mo(CO)6 with mesitylene were conducted in the presence of air, what would probably be the decomposition products? This is lab of Organometallic Synthesis: 0.5 g (~ 1.9 mmol) of Mo(CO)6 was added with 5mL (~36mmol) of mesitylene. It was then refluxed with nitrogen, precipitate with hexane, and purified with CH2Cl2. Precipitate again with hexane. The end product was 1,3,5-C6H3(CH3)3]Mo(CO)3 precipitate.
