Discussion Overview

The discussion revolves around the classification and drawing of VSEPR structures for the molecule CsF, with a focus on whether it is ionic, polar covalent, or non-polar covalent. Participants are seeking clarity on how to represent these structures and the nature of the bonding in CsF.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses confusion about what constitutes a VSEPR structure and suggests that CsF is ionic, indicating a Lewis structure with a fluoride ion depicted.
  • Another participant asserts that VSEPR theory applies only to covalent bonds, emphasizing that CsF represents a highly ionic bond.
  • A request for guidance on how to draw VSEPR structures is made, indicating a lack of understanding of the concept.
  • Participants reference external resources, such as Wikipedia, to clarify the nature of VSEPR theory and its applicability to ionic compounds.

Areas of Agreement / Disagreement

There is disagreement regarding the classification of CsF and the applicability of VSEPR theory to ionic compounds. Some participants assert that CsF is ionic, while others question how to approach the assignment given this classification.

Contextual Notes

Participants express uncertainty about the definitions and requirements for drawing VSEPR structures, particularly in relation to ionic versus covalent bonding. There are unresolved questions about how to proceed with the assignment given these distinctions.

Who May Find This Useful

Students studying chemistry, particularly those learning about molecular geometry, bonding types, and VSEPR theory.

Homework Statement



I'm supposed to draw VSEPR structures showing all valence electrons for the molecule. Draw in the partial charges δ+ and δ- if they exist. Classify the molecules as ionic, polar covalent or non-polar covalent. Some molecules may be of hypothetical existence.


Homework Equations


I want to know about CsF


The Attempt at a Solution


What exactly do they mean VSEPR structure I have never had to draw them. I assume I have to draw the actual geometry? For this one it is just linear. I don't know how to show you what I have. I actually have more of a lewis structre.
[Cs+][F-] I have fluoride ion with 6 dots around it.

So this is ionic. I have the arrow drawn from Cs going to F. Is this right? Is this what they want ?
 
Physics news on Phys.org
If you read what VSEPR is about, you'll discover that it applies only to covalent bonding between the atoms, not to ionic. The chemical bond in CsF is the most ionic one could imagine.
 
Can someone please tell me how to draw VSEPR strutures? Please

Its a bit large to cover in a single post.

Why is this so ? And I read the wikipage posted. So if I have CsF what am I supposed to do? Thanks
