  2. E–Z notation - Wikipedia

    en.wikipedia.org/wiki/E–Z_notation

    E–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry.It is an extension of cis–trans isomer notation (which only describes relative stereochemistry) that can be used to describe double bonds having two, three or four substituents.

  3. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    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]

  4. IUPAC nomenclature of chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.

  6. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...

    Names of oxyanions should in general follow the names in Table X of the IUPAC 2005 Red Book. [2] Exceptions can be made if an alternate name is much more common in the literature, e.g. xenate rather than xenonate (don't generalise this to radon though, as it would create an ambiguity between radon and radium).

  8. Absolute configuration - Wikipedia

    en.wikipedia.org/wiki/Absolute_configuration

    The R/S system is an important nomenclature system for denoting enantiomers. This approach labels each chiral center R or S according to a system by which its substituents are each assigned a priority , according to the Cahn–Ingold–Prelog priority rules (CIP), based on atomic number.

  9. Nomenclature of Organic Chemistry - Wikipedia

    en.wikipedia.org/wiki/Nomenclature_of_Organic...

    Nomenclature of Organic Chemistry, commonly referred to by chemists as the Blue Book, is a collection of recommendations on organic chemical nomenclature published at irregular intervals by the International Union of Pure and Applied Chemistry (IUPAC).
