VSEPR Theory. Valence Shell Electron Pair Repulsion (VSEPR) is a theory that states that the 3d orientation, also known as the molecular geometry, of a molecule is not dependent on its chemical formula but on the repulsion of valence electrons.In other words, two molecules with the general formulas `AB_3` may look completely different in real life: . Electron group geometry is the three-dimensional arrangement of atoms in a molecule. The geometry of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes.

The valence shell electron pair repulsion (VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion. This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another.Linear: It specifies the geometry shaped by a central atom surrounded by two other atoms. The atoms are arranged in a straight line, and the angle between the bonds, or bond angle, is 180 °. The VSEPR notation is AX 2. Examples of molecules with linear geometry are carbon dioxide (CO 2 ), beryllium chloride (BeCl 2 ), and nitric oxide (NO).
Thus, the electron-pair geometry is tetrahedral and the molecular structure is bent with an angle slightly less than 109.5°. In fact, the bond angle is 104.5°.
