Chemistry suffixes
In chemistry, suffixes play a vital role in systematically naming and describing chemical compounds. These word endings, added to a root name, provide specific information about the molecule’s type or properties.
A compound’s name is typically divided into three parts: prefix, root, and suffix.
- The root tells the number of carbon atoms (in organic compounds).
- The prefix adds details like substituents or branches.
- The suffix identifies the functional group or type of compound.

| -ate | Oxyanions with more oxygen atoms | Sulfate |
| -ite | Oxyanions with fewer oxygen atoms | Sulfite |
| -ic | Acids with higher oxidation state | Nitric acid (HNO₃) |
| -ous | Acids with lower oxidation state | Nitrous acid (HNO₂) |
| -ol | Alcohols (OH group attached to carbon) | Ethanol (C₂H₅OH) |
| -one | Ketones (C=O group within chain) | Propanone (acetone) |
