Detailed Solution

In O₂F₂, due to high electronegativity, the electron density is attracted by fluorine towards itself. This results in reduced O – O bond length. But in H₂O₂, oxygen is more electronegative than hydrogen. So, more electron density on oxygen atoms result in increased O – O bond length.
