Discussion Overview

The discussion revolves around whether f-orbitals can participate in the formation of sigma bonds. Participants explore the nature of bonding and the characteristics of f-orbitals in the context of molecular orbital theory.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions if f-orbitals can form sigma bonds, noting that they are typically considered "deep" in the atom and may not participate in bonding.
  • Another participant expresses doubt about the ability of f-orbitals to form sigma bonds, suggesting that while there may be f-orbitals with the correct symmetry, their involvement in bonding is questionable.
  • A later reply mentions a lack of information regarding f-orbital sigma bonds but suggests that f-orbitals may form delta bonds instead.

Areas of Agreement / Disagreement

Participants generally express uncertainty regarding the role of f-orbitals in sigma bonding, with no consensus reached on the matter. Some suggest that f-orbitals do not participate in sigma bonds, while others propose alternative bonding types such as delta bonds.

Contextual Notes

The discussion highlights limitations in available information about f-orbitals and their bonding capabilities, particularly regarding symmetry requirements for sigma bonds.

Homework Statement


This is not a homework question.
I found a question in my book that which orbitals form sigma bonds.
I am wondering if any of the f-orbitals form sigma bonds?

Would someone like to answer my question?
 
I don't know, but I strongly doubt.

This will be handwavy.

For sigma bond you need orbitals of a correct symmetry. Assuming there exists an f orbital of a correct symmetry (intuition tells me it does) it should be able to create sigma orbital. But f orbitals are "deep" in the atom and they don't participate in bonding.

I think you are right.
After a deep search too, i wasn't able to find any information on f-orbital sigma bonds.
But what i found is that they form delta bonds. :smile:
