  2. List of chemical compounds with unusual names - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_compounds...

    Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...

  3. Geneva Rules - Wikipedia

    en.wikipedia.org/wiki/Geneva_Rules

    When naming compounds with side chains the name would be determined by the longest straight chain with a substituted group e.g. methyl propane (CH 3 CH(CH 3)CH 3) The endings ene and ine were indicative of the presence of a double and triple bond respectively.

  4. Chemical graph generator - Wikipedia

    en.wikipedia.org/wiki/Chemical_graph_generator

    Two substructures of a caffeine molecule are given, (A) and (B). The overlap of these substructures is highlighted in green in the caffeine structure (C). Molecular structure generation is a branch of graph generation problems. [1] Molecular structures are graphs with chemical constraints such as valences, bond multiplicity and fragments. These ...

  5. IUPAC nomenclature of organic chemistry - Wikipedia

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

    To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple ...

  6. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.

  7. Longest word in English - Wikipedia

    en.wikipedia.org/wiki/Longest_word_in_English

    The IUPAC nomenclature for organic chemical compounds is open-ended, giving rise to the 189,819-letter chemical name Methionyl­threonyl threonyl . . . iso ­leucine for the protein also known as titin, which is involved in striated muscle formation. In nature, DNA molecules can be much bigger than protein molecules and therefore potentially be ...

  8. IUPAC nomenclature of chemistry - Wikipedia

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

    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)

  9. List of carboxylic acids - Wikipedia

    en.wikipedia.org/wiki/List_of_carboxylic_acids

    Numerous organic compounds have other common names, often originating in historical source material thereof. The systematic IUPAC name is not always the preferred IUPAC name , for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid.
