Concept of mixing two atomic orbitals with the same energy levels to give a degenerated new type of orbitals

Nancy Rajput 7 years, 5 months ago

Atoms rearrange their atomic orbitals when bonding to produce orbitals with shapes more suitable for the bonding process. This is called hybridisation. It is performed by almost all atoms when bonding although carbon provided the easiest examples to show. It is easy to recognise the hybridisation used by simply observing the double or triple bonds. Only single bond = sp3 hybridisation 1 double bond = sp2 hybridisation 1 triple bond = sp hybridisation
