  2. IUPAC nomenclature of chemistry - Wikipedia

    en.wikipedia.org/.../IUPAC_nomenclature_of_chemistry

    The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)

    Preferably, the name should also represent the structure or chemistry of a compound. For example, the main constituent of white vinegar is CH 3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid.

  4. IUPAC nomenclature of organic chemistry - Wikipedia

    In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]

    Heavy atom – term used in computational chemistry to refer to any element other than hydrogen and helium. Minor actinides – Actinides found in significant quantities in nuclear fuel, other than U and Pu: Np, Am, Cm. Native metals – Metals that occur pure in nature, including the noble metals and others such as Sn and Pb.

    The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.

    IUPAC is best known for its works standardizing nomenclature in chemistry, but IUPAC has publications in many science fields including chemistry, biology, and physics. [11] Some important work IUPAC has done in these fields includes standardizing nucleotide base sequence code names; publishing books for environmental scientists, chemists, and ...

  8. Trivial name - Wikipedia

    en.wikipedia.org/wiki/Trivial_name

    In chemistry, a trivial name is a non-systematic name for a chemical substance. That is, the name is not recognized according to the rules of any formal system of chemical nomenclature such as IUPAC inorganic or IUPAC organic nomenclature. A trivial name is not a formal name and is usually a common name.

  9. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
