VSEPR Theory (Molecular Shapes) A = the central atom, X = an atom bonded to A, E = a lone pair on A. Note: There are lone pairs on X or other atoms, but we don't care. We are interested in only the electron densities or domains around atom A. Total. Molecular Models (VSEPR Theory) Next VSEPR Theory (Molecular Shapes) A = the central atom, X = an atom bonded to A, E = a lone pair on A. Note: There are lone pairs on X or other atoms, but we don't care. We are interested in only the electron densities or domains around atom A. Total. The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. The five compounds shown in the figure below can be used to demonstrate how the VSEPR theory can be applied to simple molecules.
3 <109.5°. 1 “Electron groups” include bonds, lone pairs, and odd (unpaired) electrons. A multiple bond (double bond or triple bond) counts as one electron group. 2 A multiple bond (double bond or triple bond) counts as one bond in the VSEPR model.

The Unit model set 69175V is the VSEPR theory version of large model set. Each sphere is 45mm and when combined with the specially designed VSEPR "paddles", any VSEPR shape is visible even from the back row of a lecture hall. The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. The five compounds shown in the figure below can be used to demonstrate how the VSEPR theory can be applied to simple molecules. Valence Shell Electron Pair Repulsion (VSEPR) theory allows the Chemist to predict the 3-dimensional shape of molecules from knowledge of their Lewis Dot structure. In VSEPR theory, the position of bound atoms (ligands) and electron pairs are described relative to a central atom.
Valence Shell Electron Pair Repulsion Theory VSEPR theory proposes that the geometric arrangement of terminal atoms, or groups of atoms about a central atom in a covalent compound, or charged ion, is determined solely by the repulsions between electron pairs present in the valence shell of the central atom.
VSEPR theory is used to predict the arrangement of electron pairs around non-hydrogen atoms in molecules, especially simple and symmetric molecules, where these key, central atoms participate in bonding to two or more other atoms; the geometry of these key atoms and their non-bonding electron pairs in turn determine the geometry of the larger whole. # of "Effective Pairs" # of Lone pairs Geometry Shape Lewis Structure Example 3d model bond angles; 5: 0: Trigonal bipyramid: Trigonal bipyramid: video: 5-0 configuration. 120, 90, 180: 5: 1: Trigonal bipyramid: See-saw This theory is very simplistic and does not account for the subtleties of orbital interactions that influence molecular shapes; however, the simple VSEPR counting procedure accurately predicts the three-dimensional structures of a large number of compounds, which cannot be predicted using the Lewis electron-pair approach. 3 <109.5°. 1 “Electron groups” include bonds, lone pairs, and odd (unpaired) electrons. A multiple bond (double bond or triple bond) counts as one electron group. 2 A multiple bond (double bond or triple bond) counts as one bond in the VSEPR model. These ideas have been explored and have resulted in a theory for molecular geometry known as Valence Shell Electron-Pair Repulsion Theory. VSEPR focuses on the positions taken by the groups of electrons on the central atom of a simple molecule.
