Question

Statement I ($S_1$): In $O_3$ molecule both O – O bond lengths are of equal length (128 Pm ) Statement II ($S_2$): $O_3$ molecule is a non-polar molecule.

• A. Both $S_1$ and $S_2$ are correct
• B. $S_1$ is correct but $S_2$ is incorrect
• C. $S_1$ is incorrect but $S_2$ is correct
• D. Both $S_1$ and $S_2$ are incorrect

Answer 1

Answer: (B)

$S_1$ is correct but $S_2$ is incorrect

Answer 2

Statement I ($S_1$) is correct. Ozone ($O_3$) exhibits resonance, resulting in two identical O-O bonds with a bond length of 128 pm. Statement II ($S_2$) is incorrect. Ozone ($O_3$) has a bent molecular geometry and a net dipole moment, making it a polar molecule.
