The suffix -yne is used in organic chemistry to form names of organic compounds containing the -C=C- group: see acetylene. Sometimes a number between hyphens is inserted before it to state which atom the triple bond follows. It may have been come from a collapsed form of the ending of the word acetylene. The final "-e" disappears if it is followed by another suffix. ...more on Wikipedia about "-yne"
The root alk- is used in organic chemistry to form classification names for classes of organic compounds which contain a carbon skeleton but no aromatic rings. It was extracted from the word alcohol by removing the -ol suffix. See e.g. alkyl, alkane. ...more on Wikipedia about "Alk-"
Avogadro's number, also called Avogadro's Constant (NA) is a large constant used in chemistry and physics. Avogadro's number is formally defined as the number of carbon-12 atoms in 12 grams (0.012 kg) of carbon-12, which is approximately 6.023 . Historically, carbon-12 was chosen as the reference substance because its atomic mass could be measured particularly accurately. ...more on Wikipedia about "Avogadro's number"
(Aza-) The prefix -aza is used in organic chemistry to form names of organic compounds where a carbon atom is replaced by a nitrogen atom. Sometimes a number between hyphens is inserted before it to state which atom the nitrogen atom replaces. It arose by shortening the word azote, which is an old and foreign name for "nitrogen". ...more on Wikipedia about "Aza-"
For compounds found in organic chemistry, the Cahn Ingold Prelog priority rules are used to determine the orientation of a molecule for purposes of assigning stereochemistry at a stereocenter and for assigning the name of isomers of molecules possessing double bonds such as alkenes. ...more on Wikipedia about "Cahn Ingold Prelog priority rules"
A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. It identifies each type of chemical element by its element symbol and identifies the number of atoms of such element to be found in each discrete molecule of that compound. The number of atoms (if greater than one) is indicated as a subscript (although 19th-century books often used superscripts). For non-molecular substances the subscripts indicate the ratio of elements in the empirical formula. Chemical formula used for a series of compounds that differ from each other by a constant unit is called general formula. Such a series is called the homologous series, while its members are called homologs. The Hill system is a common convention for writing and sorting formulas. ...more on Wikipedia about "Chemical formula"
Cyclic aldehydes are aldehydes that have their -CHO group bonded directly to the ring. The suffix is -carbaldehyde. ...more on Wikipedia about "Cyclic aldehyde"
But in 1999 Glenn T. Seaborg died disputing the name change for #105 and was adamant about it remaining known as hahnium. His reason concerning Dubna in Russia was that he believed that they made a false claim on an element that they got credit for. When the Dubna group finally did release some additional data on the experiment, Seaborg claimed that it was a misreading of the decay pattern of their product. Even then, the Dubna group still refused to remove their claim. Some people in the Berkeley group and some others still refer to it as hahnium. ...more on Wikipedia about "Element naming controversy"
The Hill system is a system of writing chemical formulas such that the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements subsequently, in alphabetical order. When the formula contains no carbon, all the elements, including hydrogen, are listed alphabetically. ...more on Wikipedia about "Hill system"
The IUPAC International Chemical Identifier (InChI), developed by IUPAC and NIST, is a digital equivalent of the IUPAC name for any particular covalent compound. Chemical structures are expressed in terms of five layers of information – connectivity, tautomeric, isotopic, stereochemical, and electronic. ...more on Wikipedia about "International Chemical Identifier"
The International Union of Pure and Applied Chemistry (IUPAC) is an international non-governmental organization devoted to the advancement of chemistry. It has as its members national chemistry societies. It is most well known as the recognized authority in developing standards for the naming of the chemical elements and their compounds, through its Interdivisional Committee on Nomenclature and Symbols ( IUPAC nomenclature). It is a member of the International Council for Science (ICSU). ...more on Wikipedia about "International Union of Pure and Applied Chemistry"
IUPAC nomenclature is a system of naming chemical compounds and of describing the science of chemistry in general. It is developed and kept up to date under the auspices of the International Union of Pure and Applied Chemistry (IUPAC). ...more on Wikipedia about "IUPAC nomenclature"
The IUPAC Nomenclature for Transformations is a methodology for naming a chemical reaction. Traditionally a chemical reaction especially in organic chemistry is named after its inventor, the so called named reaction, to name just a few: Knoevenagel condensation, Wittig reaction or Diels-Alder reaction. A lot of reactions derive their name from the reagent involved like bromination or acylation. On rare occasions the reaction is named after the company responsible like in the Wacker process or the name only hints to the process involved like in the halogen dance rearrangement.The related IUPAC nomenclature is designed for naming organic compounds themselves. ...more on Wikipedia about "IUPAC Nomenclature for Transformations"
The IUPAC nomenclature of inorganic chemistry is a systematic way of naming inorganic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

The numerical multiplier (or multiplying affix) in IUPAC nomenclature indicates how many particular atoms or functional groups are attached at a particular point in a molecule. The affixes are derived from both Latin and Greek. ...more on Wikipedia about "IUPAC numerical multiplier"
The simplified molecular input line entry specification or SMILES is a specification for unambiguously describing the structure of chemical molecules using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules. ...more on Wikipedia about "Simplified molecular input line entry specification"
The temporary names are derived systematically from the element's atomic number. Each digit is translated to a 'numerical root', according to the table. The roots are concatenated, and the name is completed with the ending -ium. Some of the roots are Latin and others are Greek; the reason is to avoid duplicated letters. Some extra rules are designed to prevent funny-looking names. ...more on Wikipedia about "Systematic element name"
