Given below are two statements : Statement (I) : Experimentally determined oxygen-oxygen bond lengths in the O3 are found to be same and the bond length is greater than that of a O = O (double bond) but less than that of a single (O - 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 (O = O) but more than that of a single bond (O - O). In the light of the above statements, choose the correct answer from the options given below:

1. Statement I is true but Statement II is false
2. Both Statement I and Statement II are true
3. Both Statement I and Statement II are false
4. Statement I is false but Statement II is true

Correct answer: Statement I is true but Statement II is false

Solution

Statement I is accurate as it reflects the experimental findings regarding the bond lengths in ozone, which are intermediate between single and double bonds. However, Statement II incorrectly attributes the bond length characteristics solely to lone pair-lone pair repulsion, overlooking other factors such as resonance and bond order that also influence bond lengths.
