1. Systematic Nomenclature: This method uses a set of rules to create a unique and unambiguous name based on the substance's chemical structure. It's often used in chemistry and is also known as IUPAC nomenclature.
* Example: The systematic name for table salt is "sodium chloride."
2. Common Names: These names are often shorter and simpler than systematic names. They're often based on the substance's historical use or properties.
* Example: The common name for sodium chloride is "salt."
3. Trade Names: These names are given to substances by the companies that produce them. They are often used for marketing purposes and may not be related to the substance's chemical composition.
* Example: The trade name for aspirin is "Bayer."
It's important to note that the same substance can have multiple names, depending on the context and the method being used.
