Chemical compounds are made of atoms bonded together. The way the atoms are bonded together in a compound is shown by its structural formula. In this lesson, we will learn about the different types of structural formulas and look at an example for each formula.
What Is a Structural Formula?
We have chemical compounds all around us - they are in our food, drinks and in objects we use every single day. These chemical compounds can be identified by their molecular formulas. A few examples are shown in the following illustration:
Examples of common compounds and their molecular formulas
While the molecular formula shows what how many atoms there are for each element present in the compound, it does not tell us about how the elements are bonded together. We don't know which atom of an element is bonded to which. This is where the structural formula comes in.
The structural formula shows how the atoms are arranged and bonded together in a molecular formula of a chemical compound. Let's take a look at the compounds vinegar and ethyl alcohol, and compare their molecular formulas with their structural formulas:
