VSEPR lone pairsHardQuestion 600314
Question
The bond angle in H₂O (2 bond pairs, 2 lone pairs) is approximately:
- A120°
- B109.5°
- C104.5°Correct
- D107°
Correct answer
104.5°
Explanation
H₂O: 4 electron pairs. Tetrahedral electron geometry but bent molecular shape. Two lone pairs (stronger repulsion) compress the bond angle from 109.5° to 104.5°.
