1.	In which of the following compound, oxydation number of oxygen is positive ?
Answer» `BaO_(2)` `KO_(2)` FeO `F_(2)O` SOLUTION :(i) Ba, K and Fe are metals, they form `Ba^(2+),K^(+)andFe^(2+)` ions with oxygen, therefore O of `BaO_(2),KO_(2)andFeO` is negative. (ii) ELECTRONEGATIVITY of `O(3.0)ltF(4.0)`, As Oxygen has LESS electronegativity, O atom of `F_(2)O` is Positive.
