[Alexis DeHorta 2A]

What does VSEPR stand for? How does this correlate to Lewis structures and molecular shape?

[Clarence Clavite 2K]

So VSEPR stands for valence shell electron pair repulsion theory. As for how it relates to lewis structures, I believe it's why we have the elements so far apart from each other when we do the lewis dot structures. Hope this helps!

[Mihir Sukhatme 1D]

VSEPR relates to molecular shape because of electron repulsion. The repulsive properties of electrons in proximity will create distance between atoms in a molecule which will create a certain shape with certain bond angles.

VSEPR stands for Valence Electron Pair Repulsion Theory. It's the theory to predicting a molecule's molecular geometry.

[joshua_quinn_1C]

VSEPR stands for Valence-Shell Electron Pair Repulsion model. This correlates to Lewis Structures since the VSEPR model is the 3-D version of the Lewis Structure. The VSEPR model is basically a more accurately drawn version of what the molecule's shape would look like.

[Charlotte McDonough 2B]

Lewis structures are very useful for examining a molecule's structure to see location and strength of bonds between two atoms, and location of unpaired electrons. A VSEPR model is more useful for seeing the 3D shape of a molecule, which can be more useful for examining interactions between molecules, etc.

[Santiago Chang 2K]

Hi! VSEPR stands for Valence Shell Electron Pair Repulsion! Hope this helps!

[Ashley Wilson 2L]

Lewis structures only consider molecules in two-dimensional space and are therefore inaccurate representations of molecules. The VSEPR model, which stands for valence shell electron pair repulsion, is useful because it represents how molecules actually exist in three-dimensional space using geometry.

VSEPR stands for valence shell electron pair repulsion theory. This correlates to Lewis structures as it gives us the 3-D shape of a molecule that better helps us understand the geometry and bond angles.

[davis sandberg 2H]

VSEPR stands for Valence Shell Electron-Pair Repulsion Model, and is used to determine the shape and geometry of molecules. It models the repulsion between electrons (both bonded and lone pairs) around a central atom in a molecule.

[Isabelle Kim 3E]

VSEPR - valence shell electron-pair repulsion
The VSEPR theory was brought up in order to predict the general shape of a molecule using the Lewis structure. To clarify, this theory takes a step further to describe the GEOMETRICAL shape of the molecules. It provides us with more detailed description of the electron locations in the molecule through angles that also indicates the overall 3D structure.
For example, CO2 has a linear geometrical molecular shape, which means that the extending oxygen atoms are attached to the central atom (carbon) at a 180 degree angle.
Of course, there are other geometrical molecular shapes (i.e. trigonal pyramid)
It all revolves around the repulsion forces that create these shapes.

We use Lewis Structures as a guideline in order to find what VSEPR model each molecule best represents. Some examples of what we went over in class so far are: bent (Ex. H20), trigonal planar, trigonal bipyramidal, tetrahedral and octahedral! Each have different angle lengths with respect to the electron repulsion. Hope this helps!

[Alice Guey 1B]

VSEPR stands for valence shell electron pair repulsion. The VSEPR model predicts the structure of molecules based on the theory that valence shell electron pairs of atoms or just lone pairs maximize distance between each other. Certain Lewis structures are known to correspond to certain VSEPR models, so drawing Lewis structures helps predict the VSEPR model of a molecule.

[Aaron Martinez]

VSEPR stands for Valence-Shell Electron-Pair Repulsion model. Its purpose is to simulate how molecules would look in three dimensions, as opposed to Lewis structures which show molecules in two dimensions.

[Sasha Gladkikh 2A]

Hi,

Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The electrons in the valence shell of a central atom form either bonding pairs of electrons, located primarily between bonded atoms, or lone pairs. The electrostatic repulsion of these electrons is reduced when the various regions of high electron density assume positions as far from each other as possible.



It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. The electron-pair geometries describe all regions where electrons are located, bonds as well as lone pairs. Molecular structure describes the location of the atoms, not the electrons.

We differentiate between these two situations by naming the geometry that includes all electron pairs the electron-pair geometry. The structure that includes only the placement of the atoms in the molecule is called the molecular structure. The electron-pair geometries will be the same as the molecular structures when there are no lone electron pairs around the central atom, but they will be different when there are lone pairs present on the central atom.

[Kaitlyn_Urquilla_1I]

Hi! VSEPR stands for valence shell electron pair repulsion. In order to figure out molecular shape, we need to look at the Lewis structure in order to determine the number of bonds and lone pairs around the central atoms. This will help us figure out how the bonds will arrange themselves around the central atom and that helps us find out the molecular shape.

[Alice Weber 3I]

Hi, VSEPR stands for valence shell electron pair repulsion theory. There is a VSEPR chart that is really helpful to figure out the molecular shape of a molecule and in order to find the shape it is good to make a lewis structure to find out how lone pairs a molecule has.

Hey! VSEPR stands for Valence Shell Electron Pair Repulsion. We use it to find the molecular shape of different molecules. We are able to do this by looking at the central atom of a molecule and looking at the amount of bonds and lone pair electrons it has. Using VSEPR we can also figure out the angles between bonds as well as look at interactions between other molecules.

VSEPR stands for Valence Shell Electron Pair Repulsion Theory. It is the next step in determining what a molecule will look like and how the different atoms (specifically their electrons) will interact. A Lewis Structure does include bonds and lone pairs, but it does not include any information regarding molecular shape caused by electron repulsion. VSEPR does consider the interactions of electrons.

[Jessica Servoss 1H]

VSPER stands for Valence Shell Electron-Pair Repulsion Theory. Using this theory, we assume that each atom within a molecule will take on a geometrical shape that minimizes the repulsion between the valence electrons in their shells, thus giving us the many different shapes we talked about in class.

Valence Shell Electron pair repulsion model

[Parinita Jithendra 2A]

VSEPR is an acronym that stands for valence shell electron pair repulsion. It is useful for predicting and visualizing molecular structures. The structures are: linear, trigonal planar, angled, tetrahedral, trigonal pyramidal, trigonal bipyramidal, disphenoidal (seesaw), t-shaped, octahedral, square pyramidal, square planar, and pentagonal bipyramidal. To use the table you need to determine the coordination number or number of electron pairs. You should count the valence electrons of the central atom. Add an electron for each bonding atom. Subtract an electron if the central atom has a positive charge; and add an electron for a central atom with negative charge. Finally, look up your molecule on the chart by coordination number and number of atoms.

[Rebecca Preusch 2C]

VSEPR stands for valence shell electron pair repulsion. It relates to Lewis structure and shape because the repulsion of electrons causes the electron pairs to spread apart as much as they can (maximize bond angle) which results in the shape of the molecule. To relate it to lewis structure, you can think of VSEPR and shape as 3d versions of lewis structures, or as a more accurate/ in depth structure model.
