Since there are four fluorine atoms, the total oxidation number for the fluorine portion of the molecule is -4. Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2. H is less electronegative than C, so it acts with the oxidation number + 1. For CH 4 oxidation with 18 O 2, >70% of 18 O 2 molecules were incorporated in the CH 3 OH product. 3) In CH3OH, the oxidation number of C = +1, H = +1 and O = -2 -The oxidation number for O is -2 most of the time - for a neutral molecule, the sum of the oxidation number = 0.
