Choose the molecule that could not be represented by single electronic structure formula:
Correct answer: C. SO2
- A. CH4
- B. H2O
- C. SO2
- D. O2
Explanation
C is the correct option as the electronic structure of the SO2 molecule is best represented as a resonance hybrid of two equivalent structures.

About VSEPR Theory
Valence shell electron pair repulsion theory predicts molecular shape by arranging bonding pairs and lone pairs around a central atom to minimize repulsion. Questions cover linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral electron geometries, bond angles and distortions caused by lone pairs. Electron geometry is not always the same as molecular shape.
