    Anyone done IAL January 2016? I liked the paper although the boundaries are super low...
    Was it difficult or easy but low gb? Because Phy 4 was easy but had low Gb.

    Why the answer is D ?
    If you check the oxidation state of Titanium in option D, it's +6, which is not possible because the maximum oxidation state of Titanium is +4...+6 means it has lost two electrons from the stable Argon configuration.

    You want the max amount of the complex, which has one metal ion and 2 two ligands. Therefore the max is going to be when the ratio of metal to ligand is 1:2, so B (as for example if I have 50/50 then I can only have 2.5cm^3 of the metal reacting with ligand)
