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.

This Unit is Categorized into Following Topics, open the link to read.

  1. Valence Shell Electron Pair Repulsion (VSEPR) Theory
  2. Valence Bond Theory (VBT) – Shape of Molecules
  3. Difference Between Sigma (σ) and Pi (π) Bond
  4. Hybridization: Condition and Characteristics
