What is O-O bond length in ozone ?

Question

Given below are two statements :
Statement I: The boiling point of hydrides of Group 16 elements follow the order
H₂O > H₂Te > H₂Se > H₂S.
Statement II: On the basis of molecular mass, H₂O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H-bonding in H₂O, it has higher boiling point.
In the light of the above statements, choose the correct answer from the options given below :

Answer 1

Step 1: Idea:
Bond order in ozone is $1.5$, so the length should sit between the single bond value and the double bond value.

Step 2: Result:
Between $148$ pm and $121$ pm, only $128$ pm fits, which is the experimental value. The other numbers are far too large for an O-O bond.

Final Answer:
The O-O bond length in ozone is $128$ pm, option (B). \[ \boxed{128\ \text{pm}} \]
