    Introduction. This section explores how we predict the molecular and electron-pair shapes of molecules using the VSEPR (Valence Shell Electron Pair Repulsion) theory. We will first go over what VSEPR theory is and how it defines an electron-pair geometry and a molecular geometry. Then we will go over the steps for determining the electron-pair ...

    May 20, 2018 · This shape is called bent or angular. A molecule with four electron groups about the central atom orients the four groups in the direction of a tetrahedron, as shown in Figure 10.7.1 10.7. 1 Tetrahedral Geometry. If there are four atoms attached to these electron groups, then the molecular shape is also tetrahedral.

    Apr 13, 2023 · Figure 11.7.2 11.7. 2 (left to right): A three-dimensional rendering of CH 4, a tetrahedron, and the three-dimensional structure of CH 4 drawn inside a tetrahedron. The oxygen atom in a water molecule is still surrounded by four electron groups. It's just that two of those groups are lone pairs and those lone pairs still have repulsions and ...

    Lewis electron structures predict the number and types of bonds, whereas VSEPR can predict the shapes of many molecules and polyatomic ions. We can use the VSEPR model to predict the geometry of most polyatomic molecules and ions by focusing on only the number of electron pairs around the central atom, ignoring all other valence electrons present.

    Mar 1, 2012 · The shape of a molecule affects how it interacts with other molecules and that in turn can give rise to all kinds of interesting phenomena. One important area is how drugs work in the body. Using this as an example, the drug – a molecule with a specific shape – will commonly interact with a larger molecule, such as a protein.
