Limitation to valence bond theory (VBT) is that:
Correct answer: C. It doesn't explain paramagnetic behavior of O2
- A. It doesn't address the shapes of the molecules
- B. It doesn't involve the criteria of bond formation
- C. It doesn't explain paramagnetic behavior of O2
- D. None of the above
Explanation
Paramagnetic behaviour of oxygen is explained by MOT not VBT.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
