NEET2003ChemistryHydrogenActual
Assertion : The O - O bond length in H ₂ O ₂ is shorter than that of O ₂ ~F ₂ . Reason : H ₂ O ₂ is an ionic compound.
Options
- AIf both assertion and reason are true and the reason is the correct explanation of the assertion
- BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
D. If both assertion and reason are false.
Step-by-step solution
O ₂ ~F ₂ has the similar structure as that of H ₂ O ₂ but the O - O bond length is shorter in O ₂ ~F ₂ than in H ₂ O ₂ . This is due to the high electronegativity of attached F-atoms.
