What is the oxidation no. of oxygen is O2F2Select an answerA–2B–1C+1D+2

The oxidation number of oxygen in O2F2 is +1.

Here's the step-by-step explanation:

1. The oxidation number of Fluorine (F) is always -1 in its compounds because it is the most electronegative element.

2. In O2F2, there are two Fluorine atoms, so the total oxidation number for Fluorine is -2 (-1*2).

3. The total oxidation number of a neutral compound is zero.

4. Therefore, the total oxidation number for the two Oxygen atoms in O2F2 must be +2 (to balance the -2 from Fluorine and make the total oxidation number zero).

5. Since there are two Oxygen atoms, the oxidation number for each Oxygen atom is +1 (+2/2).

So, the answer is C+1.
