Geometry of Molecules
The Specific arrangement of atoms in molecule and the bond angles determines the shape of particular molecule. Modern techniques such as X-ray diffraction and electron diffraction are used to determine the geometry of molecule.

The various theories are employed to decide the shape of molecules, which are as follows:

1. Valence shell electron pair repulsion theory (VSEPR theory)
2. Valance bond theory (VBT theory)
3. Molecular orbital theory (MOT)

Out of these, only first two are discussed here.
