The Lewis structure helps us identify the bond pairs and the lone pairs. Then, with the Lewis structure, we apply the valence-shell electron-pair repulsion (VSPER) theory to determine the molecular geometry and the electron-group geometry.

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.

In summary, the three possible orientations of electron groups around an atom that obeys the octet rule are the following. 6.1-5. Bond Angles. If all of the electron groups around a central atom are not identical, the predicted bond angles are only approximate.

Aug 14, 2010 · Electron pairs repel – this applies both to bonding electrons and electrons in lone pairs. So molecules will adopt a geometry which maximizes the distance between them. This is why methane is tetrahedral, (internal angles 109°) and not square planar (internal angles 90°), and water is bent, not linear.
