Question

Give reason â Bonds in ozone are equivalent. (CBMS)

Answer 1

However, the experimentally determined O-O bond lengths in ozone are same and is found to be in between them i.e. at 128 pm, Due to resonance the two bonds in ozone are a resonance hybrid of a single and double bond.

Hence, bonds in the ozone are equivalent

Answer 2

In oxygen the three oxygen atoms are arranged in a bent shape the central oxygen atom makes one single bond with a terminal oxygen atom and double bond with the outer terminal oxygen atom but the electron of double bond are delicate over the three oxygen atom due to which the single and double bond are not entirely pure giving rise to the oxygen oxygen bond distance and average has distance of the single and double bond.
