In which of the following the oxidation number of oxygen has been arrangd in increasing order :-

Options

A. `OF_(2) lt KO_(2) lt BaO_(2) lt O_(3)`
B. `BaO_(2) lt KO_(2) lt O_(3) lt OF_(2)`
C. `BaO_(2) lt O_(3) lt OF_(2) lt KO_(2)`
D. `KO_(2) lt OF_(2) lt O_(3) lt BaO_(2)`

Answer

B

Explanation

Oxidation no. of oxygen in `OF_(2)implies x+(-2)=0implies x=+2`
Oxidation no. of oxygen in `KO_(2) implies (+1)+2x=0 implies x=-1//2`
Oxidation no. of oxygen in `BaO_(2) implies (+2)+2x=0 implies x=-1`
Oxidation number of oxygen in `O_(3)=0`
`:.` Correct order is
`BaO_(2) lt KO_(2) lt O_(3) lt OF_(2)`.
