Which of the following is not a valid condition for hybridisation?
The orbitals present in the valence shell of atoms undergo hybridisation.
Only half filled orbitals participate in hybridisation.
The orbitals undergoing hybridisation should have almost equal energy.
In some cases, even completely filled orbitals of valence shell take part in hybridisation
It is not necessary that only half filled orbitals participate in hybridisation.
