Elemental oxidation states

The first step in finding the oxidation states (or oxidation numbers) in potassium 3-carboxyphenyltrifluoroborate is to draw the structure diagram. Next set every oxidation number equal to the atom's formal charge:  In potassium 3-carboxyphenyltrifluoroborate 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 boron-carbon bond, 3 boron-fluorine bonds, 2 carbon-oxygen bonds, and 7 carbon-carbon bonds. For each of these bonds, assign the bonding electrons to the most electronegative element.  First examine the boron-carbon bond: element | electronegativity (Pauling scale) |  B | 2.04 |  C | 2.55 |   | |  Since carbon is more electronegative than boron, 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 boron accordingly:  Next look at the boron-fluorine bonds: element | electronegativity (Pauling scale) |  B | 2.04 |  F | 3.98 |   | |  Since fluorine is more electronegative than boron, the electrons in these bonds will go to fluorine:  Next look at the carbon-oxygen bonds: element | electronegativity (Pauling scale) |  C | 2.55 |  O | 3.44 |   | |  Since oxygen is more electronegative than carbon, the electrons in these bonds will go to oxygen:  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  -2 | O (oxygen) | 2  -1 | C (carbon) | 5  | F (fluorine) | 3  0 | C (carbon) | 1  +1 | H (hydrogen) | 5  | K (potassium) | 1  +3 | B (boron) | 1  | C (carbon) | 1
