  2. End group - Wikipedia

    en.wikipedia.org/wiki/End_group

    The thiocarbonate moiety can be functionalized at the R-group for end group analysis. The end group is a result of the propagation of chain-transfer agents during the free-radical polymerization process. The end groups can subsequently be modified by the reaction of the thiocarbonylthio compounds with nucleophiles and ionic reducing agents. [11]

    Example: 2,2,3-trimethyl- . If there are both double bonds and triple bonds, "en" (double bond) is written before "yne" (triple bond). When the main functional group is a terminal functional group (a group which can exist only at the end of a chain, like formyl and carboxyl groups), there is no need to number it.

  4. Pendant group - Wikipedia

    en.wikipedia.org/wiki/Pendant_group

    In IUPAC nomenclature of chemistry, a pendant group (sometimes spelled pendent) or side group is a group of atoms attached to a backbone chain of a long molecule, usually a polymer. Pendant groups are different from pendant chains, as they are neither oligomeric nor polymeric. [2] For example, the phenyl groups are the pendant groups on a ...

  5. Compendium of Analytical Nomenclature - Wikipedia

    en.wikipedia.org/wiki/Compendium_of_Analytical...

    The Compendium of Analytical Nomenclature is an IUPAC nomenclature book published by the International Union of Pure and Applied Chemistry (IUPAC) containing internationally accepted definitions for terms in analytical chemistry. [1] It has traditionally been published in an orange cover, hence its informal name, the Orange Book.

  6. Acyl group - Wikipedia

    en.wikipedia.org/wiki/Acyl_group

    In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group ( R−C=O ) or hydrogen in the case of formyl group ( H−C=O ).

  7. 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.

    3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [1] [2] and the Red Book, [3] respectively.

    IUPAC organic nomenclature has three basic parts: the substituents, carbon chain length, and chemical affix. [13] The substituents are any functional groups attached to the main carbon chain. The main carbon chain is the longest possible continuous chain. The chemical affix denotes what type of molecule it is.
