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

1. X-shorter, Y-Shorter
2. X-shorter, Y-longer
3. X-longer, Y-Shorter
4. X-longer, Y-longer

Correct answer: X-longer, Y-Shorter

Solution

The O–O bond in H2O2 is longer than in F2O2 due to the presence of steric hindrance and electron repulsion from the larger fluorine atoms, which shortens the O–F bond. Additionally, the O–H bond in H2O2 is shorter than the O–F bond in F2O2 because the electronegativity of fluorine pulls electron density away, resulting in a longer bond.
