If the following orbitals are hybridized, then the number of hybrid orbitals will be:
2s, 2px, 2py, 2pz
4
Always remember,
Number of hybrid orbitals = Number of orbitals involved in hybridization.
Here, number of orbitals involved = 4
2s 2px 2py 2pz
∴ Number of hybrid orbitals = 4
4 sp3 hybrid orbitals
