Explains the 3-D shape of molecules.
There are two main factors in a molecule’s shape:
Electron Domain Geometry – how many places can electrons be found on the central atom?
Bonding Domain Geometry – how many places can bonds be found?
Comparing these two gives us a molecule’s shape.VSEPR Theory
The number of electron domains, or how many “places” electron pairs are found, determines part of the 3-D shape.
Double and triple bonds count as a single electron domain.Electron Domains
4 electron domains – tetrahedral
Bond angle: 109.5º
3 electron domains – trigonal planar
Bond angle: 120º
2 electron domains – linear
Bond angle: 180ºElectron Domain Geometry
