There are various ways of drawing this and you will need to be familiar with all of them.Ī displayed formula shows all the bonds in the molecule as individual lines. In cases like this, the bonding in the organic molecule isn't important.Ī structural formula shows how the various atoms are bonded. ![]() About the only place where you might come across them is in equations for the combustion of simple hydrocarbons, for example: Molecular formulae are very rarely used in organic chemistry, because they don't give any useful information about the bonding in the molecule. This page explains the various ways that organic molecules can be represented on paper or on screen - including molecular formulae, and various forms of structural formulae.Ī molecular formula simply counts the numbers of each sort of atom present in the molecule, but tells you nothing about the way they are joined together.įor example, the molecular formula of butane is C 4H 10, and the molecular formula of ethanol is C 2H 6O.
