Discussion Overview

The discussion revolves around the hybridization of orbitals in the formation of certain chemical compounds, specifically PCl5, SF6, and IF7. Participants explore the validity of hybridization theories, particularly the involvement of d orbitals in main group compounds.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant asserts that during the formation of PCl5, the hybridization is sp^3d and questions which d orbitals are used in sp^3d^2 and sp^3d^3 hybridization for SF6 and IF7.
  • Another participant claims that the theory of d-orbitals contributing to hybridization in main group compounds has been proven wrong, suggesting that d-orbitals are energetically too high to participate.
  • Some participants seek clarification on the new theory regarding the formation of SF6 and IF7, indicating a desire for an explanation based on updated understanding.
  • A later reply introduces the concept of valence bond theory and mentions describing bonding in terms of resonating bonds.

Areas of Agreement / Disagreement

Participants express disagreement regarding the role of d orbitals in hybridization, with some asserting that the traditional theory is incorrect while others seek further clarification on the implications of this claim.

Contextual Notes

The discussion reflects uncertainty regarding the validity of hybridization theories and the specific roles of d orbitals in bonding, with no consensus reached on the new theoretical framework.

Hi. During the formation of PCl5, the hybridisation is sp^3d and the dz^2 oribital is used. But in the cases of sp^3d^2 and sp^3d^3 hybridisation, like in the formation of SF6 and IF7 respectively, which of the d orbitals out of the five are used to make the hybrid orbital?
Thanks!

This theory has long been proven wrong. In the formation of main group compounds, d-orbitals are energetically too high to contribute in hybridization.

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!

In terms of valence bond theory, which you seem to be learning at the moment, you would describe bonding in terms of resonating bonds.

Oh! Thank you!
