VSEPR Theory
- Valence Shell Electron Pair Repulsion Theory
- Predicts the geometry of molecules based on electron pair repulsion
- Lone pair/Lone pair repulsions are greater than lone pair/bonding pair repulsions, which are greater than bonding pair/bonding pair repulsions
- Lone pairs try to maximize distance from each other
- Multiple bonds are treated as single bonds for VSEPR theory
- Examples:
- CH4 (methane)
- SO32- (sulfite)
- H2O (water)
- NH3 (ammonia)
