The discussion centers on the hybridization of molecules such as PCl5, SF6, and IF7. It establishes that PCl5 undergoes sp3d hybridization, utilizing the dz2 orbital, while the traditional view of sp3d2 and sp3d3 hybridization for SF6 and IF7 has been challenged. The consensus is that d-orbitals are energetically too high to contribute to hybridization in main group compounds, thus invalidating previous theories. The current understanding emphasizes valence bond theory and resonating bonds as the basis for explaining the formation of these compounds.

This theory has been proven wrong? What does the new theory state? With the new theory could you please explain how SF6 and IF7 forms?DrDu said:This theory has long been proven wrong. In the formation of main group compounds, d-orbitals are energetically too high to contribute in hybridization.
In terms of valence bond theory, which you seem to be learning at the moment, you would describe bonding in terms of resonating bonds.Priyadarshini said:This theory has been proven wrong? What does the new theory state? With the new theory could you please explain how SF6 and IF7 forms?
Thanks!
