What is VSPER? What do you use it for?

VSEPR model explains how to draw the 3D shape of molecules. It stands for Valence Shell Electron Pairs Repel, which summarizes how to draw them--you want to draw the models in a way that will minimize electron repulsion. From the VSEPR model, you can determine the molecular shape and its name.

I hope this helps!

Hi, VSPER stands for Valence Shell Electron Pair Repulsion Model, and we use this rule to determine the shape of the molecule. As the name implies, this rule determines where bonding electrons and lone pairs will be in respect to the central atom.

VSPER stands for valence shell electron pair repulsion, "it is used to predict the the geometry of individual molecules from the number of electron pairs surrounding their central atom"

The VSEPR theory, sometimes pronounced 'vesper', stands for Valence Shell Electron Pair Repulsion. It states that repulsion between the sets of electron bond pairs surrounding an atom in a compound causes these sets to be oriented as far apart as possible, giving the compound a certain shape. It's basically the shape of the bonds.

VSEPR stands for Valence Shell Electron Pair Repulsion and it is used to help determine the geometrical shape of a particular molecule. Since electrons repel each other, VSEPR assumes that a molecule will have a shape that minimizes these repulsions. In class Dr. Lavelle said that lone pair-lone pair electron repulsions are stronger than lone pair - bound pair electron repulsions which are stronger than bound pair- bound pair electron repulsions. You use these rules to figure out the shape of a molecule.

The VSPER model helps explain the shape of molecules that have been determined by experiments. Previously, we have just been drawing the structures without paying much attention to the distance between the atoms, but using the VSPER model we can find the exact angular distance between each atom.

VSEPR model explains experimenetally observed shape of molecules. Whereas the Lewis Structure just show a 2D representation of molecular shape and indicates approximate location of bonding.
