Easy MCQ +4 / -1 PYQ · JEE Mains 2025

Given below are two statements :

Statement (I) : Experimentally determined oxygen-oxygen bond lengths in the $\mathrm{O}_3$ are found to be same and the bond length is greater than that of a $\mathrm{O}=\mathrm{O}$ (double bond) but less than that of a single $(\mathrm{O}-\mathrm{O})$ bond.

Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond $(\mathrm{O}=\mathrm{O})$ but more than that of a single bond $(\mathrm{O}-\mathrm{O})$.

In the light of the above statements, choose the correct answer from the options given below :

  1. A Statement I is false but Statement II is true
  2. B Both Statement I and Statement II are true
  3. C Statement I is true but Statement II is false Correct answer
  4. D Both Statement I and Statement II are false

Solution

<p>Due to resonance bond length is identical in ozone. Therefore statement I is true and statement II is false.</p>
