- Orbitals on a single atom only would undergo hybridization.
- The orbitals involved in hybridisation should not differ largely in their energies.
- The number of hybrid orbitals formed is equal to the number of hybridising orbitals.
- The hybrid orbitals form stronger directional bonds than the pure s, p, d atomic orbitals.
- It is the orbitals that undergo hybridisation and not the electrons.
- Concept of hybridisation is useful in explaining the shape of molecules.
