  2. Moiety (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Moiety_(chemistry)

    In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

  4. Moiety - Wikipedia

    en.wikipedia.org/wiki/Moiety

    Moiety (chemistry), a part or functional group of a molecule Moiety conservation, conservation of a subgroup in a chemical species; Other uses.

  5. 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).

    For example, methyl p-hydroxybenzoate contains a phenol functional group within the acyl moiety, which in turn is part of the paraben moiety This would make more sense to say the paraben moiety contains both a phenol functional group and acyl moiety. A phenol functional group is not contained within an acyl moiety or vice versa.

  7. 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]

    en.wikipedia.org/wiki/Clar's_rule

    Some such structures may contain aromatic π-sextets, namely groups of six π-electrons localized in a benzene-like moiety and separated by adjacent rings through C–C bonds. An aromatic π-sextet can be represented by a circle, as in the case of the anthracene molecule (below). Clar's rule states that for a benzenoid polycyclic aromatic ...

  9. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry , alcohols and carboxylic acids contain one or more hydroxy groups.
