If 2s, 2px, 2py, 2pz orbitals are hybridized, then the number of hybrid orbitals will be ______.
∙ Two or more orbitals of comparable energy intermix to form same number of hybrid orbitals having equal energies and same shape. Hence, number of hybrid orbitals = Number of orbitals undergoing hybridisation.
∙ Here, four orbitals namely 2s, 2px, 2py, 2pz participate in hybridisation. Therefore four new sp3 hybrid orbitals are formed.
