IUPAC nomenclature
When we're trying to talk about different chemicals or molecules, it can get pretty confusing because there are so many of them and they can have really tricky names. That's where IUPAC nomenclature comes in to help!
IUPAC stands for the International Union of Pure and Applied Chemistry. They have made some rules to help us name molecules in a way that is clear and easy to understand.
First, we look at the types of atoms that are in the molecule. We know that each element has its own special name and abbreviation, so we use those to describe the atoms in the molecule. For example, if we have a molecule that has two oxygen atoms and one carbon atom, we know that it's made of carbon and oxygen, so we can call it "carbon dioxide" because that tells us what elements are in it.
Second, we need to figure out how many of each type of atom there are in the molecule. We can count the atoms and write them as subscripts next to the element symbol. For example, if we have a molecule with three carbon atoms and eight hydrogen atoms, we can write that as "C3H8".
Finally, we need to make sure we're using the right prefixes to describe the number of each type of atom. If we have two oxygen atoms in our molecule, for example, we would use the prefix "di-" to describe that. So our molecule would be called "carbon dioxide" because it has one carbon atom and two oxygen atoms.
Overall, IUPAC nomenclature is just a set of rules that helps us name molecules in a clear and consistent way by using the elements and the number of each type of atom in the molecule.
