The Lewis diagrams are a two-dimensional representations of covalent bonds and the VSEPR models show how the molecule could exist in three dimensional space. VSEPR is the acronym for Valence Shell Electron Pair Repulsion theory. VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom.

VSEPR THEORY Valence Shell Electron Pair Repulsion Theory What is the VSEPR Theory? The VSEPR Theory is used to predict the shapes of molecules based on the repulsion of the bonding and non-bonding electrons in the molecule. The shape is determined by the number of bonding and non-bonding electrons in the molecule. The Valence Shell Electron Pair Repulsion (VSEPR) model: • is based on the number of regions of high electron density around a central atom ( effective pairs ). • can be used to predict structures of molecules or ions that contain only non-metals by minimizing the electrostatic repulsion between the regions of high electron density. Figure 7.1 A covalent H-H bond is the net result of attractive and repulsive electrostatic forces. The nucleus-electron attractions (blue arrows) are greater than the nucleus-nucleus and electron-electron repulsions (red arrows), resulting in a net attractive force that holds the atoms together to form an H2 molecule. For a theory to be accepted, it must explain experimental data and be able to predict behavior. For example, VSEPR theory has gained widespread acceptance because it predicts three-dimensional molecular shapes that are consistent with experimental data collected for thousands of different molecules. valence shell electron pair repulsion theory. hybridization of atomic orbitals . we can "determine" geometry using: dipole moment measurements. sometimes more than one geometry is consistant with measurement. x-ray analysis. only works for certain compounds . valence shell electron pair repulsion theory (vsepr) VSEPR •Valence Shell Electron Pair Repulsion (VSEPR) theory can be used to predict the geometric shapes of molecules. •VSEPR revolves around the principle that electrons repel each other. •One can predict the shape of a molecule by finding a pattern where electron pairs are as far from each other as possible.
