Question

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: (A) Statement I is true but statement II is false (B) Both Statement I and statement II are true (C) Statement I is false but statement II is true (D) Both statement I and statement II are false

Answer: A

💡 Solution & Explanation

Resonance is responsible for the fact that bond length in ozone lies in between O–O and O=O.
