Elemental oxidation states
![The first step in finding the oxidation states (or oxidation numbers) in trichloro(pentamethylcyclopentadienyl)titanium(iv) is to draw the structure diagram. Next set every oxidation number equal to the atom's formal charge: In trichloro(pentamethylcyclopentadienyl)titanium(iv) hydrogen is not bonded to a metal with lower electronegativity, so it will have an oxidation state of +1. Any element bonded to hydrogen gains the bonding electrons, decreasing their oxidation state by 1 for every bond: With hydrogen out of the way, look at the remaining bonds. There are 1 carbon-titanium bond, 3 chlorine-titanium bonds, and 10 carbon-carbon bonds. For each of these bonds, assign the bonding electrons to the most electronegative element. First examine the carbon-titanium bond: element | electronegativity (Pauling scale) | C | 2.55 | Ti | 1.54 | | | Since carbon is more electronegative than titanium, the electrons in this bond will go to carbon. Decrease the oxidation number for carbon (by 1 for single bonds, 2 for double bonds, and 3 for triple bonds), and increase the oxidation number for titanium accordingly: Next look at the chlorine-titanium bonds: element | electronegativity (Pauling scale) | Cl | 3.16 | Ti | 1.54 | | | Since chlorine is more electronegative than titanium, the electrons in these bonds will go to chlorine: Next look at the carbon-carbon bonds: element | electronegativity (Pauling scale) | C | 2.55 | C | 2.55 | | | Since these elements are the same the bonding electrons are shared equally, and there is no change to the oxidation states: Now summarize the results: Answer: | | oxidation state | element | count -3 | C (carbon) | 5 -1 | C (carbon) | 1 | Cl (chlorine) | 3 0 | C (carbon) | 4 +1 | H (hydrogen) | 15 +4 | Ti (titanium) | 1](../image_source/875d41c8bd2c80c19473d4284085d256.png)
