Give the oxidation number of all elements in CH3COOH? In my book the oxidation number of oxygen in this compound is -1? How

Expert Answer:

1. A free element has zero oxidation number
2. Oxygen always has oxidation number -2, except peroxide (H2O2) where it is -1 and with fluorine like OF2 it is +2.
3. When hydrogen is combined with a non-metal then its oxidation number is +1, but in case of metals, its oxidation number is -1.
4. The algebraic sum of oxidation numbers of elements in a compound is zero.
