Assertion : O ₂ has higher bond length than O ₃ . Reason: O ₃ is paramagnetic.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

The resonance forms do not show any unshared electrons. Hence, O ₃ , molecule does not show any paramagnetic properties. The bond length decreases as bond order increases. Hence, bond length of O ₃ is higher than O ₂ .
