Define hybridization and explain why was it introduced?
Hybridization may be defined as the phenomenon of combining of orbitals of an atom of nearly equal energies, giving rise to entirely new orbitals equal in number to the mixing orbitals having same energy and identical shapes.
By valence bond theory, only half filled orbitals can take part in bonding.
Hybridization was introducedto explain molecular structure when the valence bond theory failed to correctly predict them.
Taking example of a CH4molecule,
without hybridization concept, the orbitals...
