A prefix to the name comes before the molecule. The prefix of the molecule’s name is based on the number of carbon atoms. For example, a chain of six carbon atoms would be named using the prefix hex-. The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule.
