Discussion Overview

The discussion revolves around the hybridization states of sulfur in SO2 and selenium in SeO2, exploring the reasons behind the differing hybridization and the implications of molecular structure and state (gaseous vs. solid).

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant asserts that the hybridization of sulfur in SO2 is sp2 because it is a discrete molecule in the gaseous state.
  • Another participant questions the basis of the hybridization claims, suggesting that differences in bond angles may not justify the hybridization types.
  • A third participant states that selenium in SeO2 has sp3 hybridization due to its solid, polymeric structure, which includes zig-zag chains.
  • One participant challenges the reasoning in the book, suggesting that the bond angles in SO2 and SeO2 should be emphasized over hybridization, and proposes that assuming no hybridization for solid SeO2 might be more accurate.

Areas of Agreement / Disagreement

Participants express disagreement regarding the hybridization states and the implications of molecular structure and state, with no consensus reached on the validity of the claims made by the book or the interpretations of hybridization.

Contextual Notes

There are limitations regarding the assumptions made about hybridization and the definitions of molecular states, as well as the reliance on bond angles without observable evidence of hybridization.

Hybridisation of SO2 and SeO2

Why is the hybridisation of S in SO2 sp2 where as it is sp3 in SeO2 ?
 
Chemistry news on Phys.org


Who sais so? Or is this only based on some difference in bond angle?
 


My book.
"SO2 being a discrete molecule exists in the gaseous state. Hybridisation of S in SO2 in the gaseous state is sp2.

Selenium and tellurium dioxides are solids having polymeric chain or layer structure. It consists of a zig-zag chain. Hybridisation of Se in SeO2 is sp3"
 


What does this book want to tell us? That SO2 doesn't exist in liquid or solid form because it is a discrete molecule?
What you can say is that the bond angles in SO2 and SeO2 are about 120 deg in gas phase and in solid SeO2 between 90 and 100 degree. Would be much more honest than speculating about some hypothetical hybridization which is not observable.
In case of SeO2 (solid) assuming no hybridization at all would probably describe the molecule even better.
Get a better book.
