Study Notes
Importance of Nomenclature
- Agreed nomenclature is essential for efficient communication in chemical sciences, industry, and regulations associated with import/export and health and safety.
IUPAC Recommendations
- IUPAC provides recommendations on various aspects of nomenclature.
Organic Nomenclature
- Basics of organic nomenclature are summarized in this document.
- Companion documents are available for inorganic and polymer chemistry.
Comprehensive Resources
- Principles of Chemical Nomenclature provides an overall summary of chemical nomenclature.
- Nomenclature of Organic Chemistry (Blue Book) provides comprehensive detail on organic nomenclature.
- Similar publications are available for inorganic compounds (Red Book) and polymers (Purple Book).
Complexity of Nomenclature
- Many compounds may have non-systematic or semi-systematic names.
- IUPAC rules allow for more than one systematic name in many cases.
- Traditional names (e.g. styrene, urea) are also used within systematic nomenclature.
Preferred IUPAC Name (PIN)
- The new edition of the Blue Book incorporates a hierarchical set of criteria for choosing the single name preferred for regulatory purposes, known as the PIN.
