VSEPR Models and Resonance Structures

Postby Beatrice Petelo 1F » Fri Nov 23, 2018 3:40 pm

Do we take into account resonance structures when determining the lewis structure and vsepr model of a molecule?

When determining lewis structure resonance you should keep resonance in mind but it does not affect VSEPR models. The number of electron densities around the central atom is the same in all the resonance structures and those regions of e- density determine the VSEPR model. So they if the regions of e- density are the same for all, the shape will be the same.

For Lewis structures, it is best to consider resonance (resonance can help us determine bond angles). For the VSEPR model, resonance does not matter because each resonance structure has the same amount of regions of electron density. Moreover, double and triple bonds act the same as a single bond in the VSEPR model for determining molecular shape.

No, resonance structures do not effect the determination of lewis structure and vsepr models of molecules.

when can resonance structures help with drawing other models?
