Water has oxygen bonded to two hydrogens, with two lone pairs on the central oxygen. These lone pairs occupy more space than bonding pairs.
The H-O-H bond angle in water is approximately:
- A
109.5°
- B
180°
- C
120°
- Dcheck_circle
104.5°
Explanation
Two lone pairs compress the H-O-H angle below the ideal tetrahedral 109.5° to about 104.5°.
