alleryThe VSEPR categories depend on whether the central atom has a:
ANet charge
BSpare mass
CLone pair
DNeutron
Answer & Solution
Correct answer: C. Lone pair
1. Bonding pairs and lone pairs repel differently.
2. The presence of lone pairs changes the geometry.
3. So the categories depend on lone pairs on the central atom.
