Which of the following statement is not correct about the structures of ozone and sulphur dioxide?
Show Hint
Ozone and sulphur dioxide are both bent molecules with resonance, but their bond angles are not exactly equal.
Updated On: Jun 17, 2026
- Both have angular shape
- Both have resonance structures
- Both have same hybridization
- Both have same bond angles
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Both ozone (\(O_3\)) and sulphur dioxide (\(SO_2\)) possess bent (angular) geometries and resonance structures. However, their bond angles are not identical.
Step 1: Shape of ozone Ozone has a bent geometry due to the presence of a lone pair on the central oxygen atom. \[ \angle O-O-O \approx 117^\circ \] Thus statement (A) is correct.
Step 2: Resonance Ozone exhibits resonance: \[ O=O-O \leftrightarrow O-O=O \] Similarly, \(SO_2\) also exhibits resonance. Hence statement (B) is correct.
Step 3: Hybridization The central atoms in both molecules are generally described as \(sp^2\) hybridized. Hence statement (C) is correct.
Step 4: Bond angles For \(SO_2\), \[ \angle O-S-O \approx 119^\circ \] For \(O_3\), \[ \angle O-O-O \approx 117^\circ \] The bond angles are different. Therefore the incorrect statement is: \[ \boxed{\text{Both have same bond angles}} \]
