O – O bond length in H₂O₂ is X than the O – O bond length in F₂O₂.The O – H bond length in H₂O₂ is Y than that of the O – F bond in F₂O₂.
Choose the correct option for X and Y from those given below

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.
