Learn how to predict the molecular geometry of a chemical compound. This video explains how different molecular shapes can be determined, such as: linear, trigonal, tetrahedral, trigonal pyramidal, angular, and others. The structures of molecules play a very important role in determining their properties. For example, taste is directly related to molecular structure. This is particularly important for biological molecules: a small change in the structure of a large biomolecule can completely destroy its usefulness to a cell and even change the cell from normal to cancerous. There are currently various experimental methods for determining molecular structure—that is, the three-dimensional arrangement of atoms. These methods should be used when precise information about the structure is required. However, it is often useful to be able to predict the approximate molecular structure of a molecule. This section considers a simple model that allows this to be done. This model, called the valence shell electron pair repulsion (VSEPR) model, is useful for predicting the molecular structures of molecules formed from nonmetals. The main idea of this model is that the structure around a given atom is determined by minimizing the repulsions between electron pairs. This means that the bonding and nonbonding electron pairs (lone pairs) around a given atom are positioned as far apart as possible.
