Experimentally, both O–O bonds in ozone (O₃) are found to be of equal length (128 pm), intermediate between O–O single (148 pm) and O=O double (121 pm). This is best explained by:
AThe molecule's bent shape
BResonance between two canonical structures
CHydrogen bonding
DHybridisation of d orbitals
Answer & Solution
Correct answer: B. Resonance between two canonical structures
Neither canonical structure (single-single or single-double) matches the observation that both O–O bonds are *identical*. The **resonance hybrid** of the two canonical forms averages the bond character, giving equal intermediate-length bonds.
