How to Find Out Hybridisation | Hybridization

For the Preparation of JEE mains , NEET , Class 12 & Class 12 Chemistry the Hybridization is a very important COncept .

HYBRIDIZATION is defined  as the  intermixing of atomic  orbitals  belongings to same atom but having  slightly different energies so that redistribution of energies takes place b/n them & resulting  in the formation of new orbitals of equal energies and  identical shape.

The orbital thus formed is known as hybridized orbital shape of hybrid orbitals.


  1. The steric numberof a molecule is the number of atoms bonded to the central atom of a

molecule plus the number of lone pairs on the central atom

It is often used in VSEPR theory (valence shell electron-pair repulsion theory) in order to determine the particular shape, or molecular geometry, that will be formed.


By  steric number we can Predict Hybridisation .

S.No.                       Hybridisation

2                               sp

3                               sp2

4                               sp3

5                               sp3d



Number of sigma bond attached to a carbon represent the number of orbitals involved in hybridization.

Practice Question for JEE & NEET :
