How To Easily Determine Hybridization Of An Atom: Orgo With Mayya

Hybridized Orbital Theory was developed to correctly account for the geometry of molecules and the bond angles. According to this theory, when an atom forms bonds in a molecule, its atomic orbitals mix together to form hybrid orbitals. Examples of hybrid orbitals are sp, sp2, and sp3.

An sp orbital is formed from the mix of an s and one p orbital.

Sp2 is formed when one s and two p orbitals mix ( px, py)

Sp3 is formed when one s and three p orbitals mix (px, py, and pz)

To correctly determine hybridization, we must fist figure out the steric number.

Steric Number = Number of Attachments + Number of Electron Lone Pairs

When steric number is 2, hybridization is sp

When steric number is 3, hybridization is sp2

When steric number is 4, hybridization is sp3

Exception: When an atom that appears to be sp3 hybridized has a lone pair adjacent to a pi bond, that atom is in fact sp2 hybridized.


Steric Number = number of attachments + number of lone pairs
