What is non hybrid orbital?

Apramey Kulkarni  Follow

In hybridization theory of covalent bonding orbitals mixed together to form hybrid orbitals (having same energy and same shape) however not each time all of the orbitals mixed together but some of them remain unhybrid (resulting in the formation of pi bonds), these are called unhybrid orbitals.

lets discuss some examples.

Ethyne molecule: In the picture below here you can see that two of p-orbitals are not taking part in hybridization and forming pi bonds.

We use hybrid orbitals when they are convenient. Hybrid atomic orbitals are a basis set that is useful to describe bonding in certain contexts. In other contexts, they are not as convenient as a different description, such as MO theory or even Lewis structures.

See some of my previous answers on hybrid orbitals, collected here:
