8.4 Electron Domain Geometry and Molecular Geometry
VSEPR Theory (Valence Shell Electron Pair Repulsion)
Electron pairs, being negatively charged, repel each other to be as far apart as possible around the central atom.
| Electron Domains | Electron Domain Geometry | Bond Angles |
|---|---|---|
| 2 | Linear | 180° |
| 3 | Trigonal Planar | 120° |
| 4 | Tetrahedral | 109.5° |
*Lone pairs of electrons reduce bond angles slightly.
Provide electron domain and molecular geometries for the following:
