What are the important characteristic features of hybridisation?

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