In organic chemistry, "sulfide" usually refers to the linkage C–S–C, although the term thioether is less ambiguous. For example, the thioether dimethyl sulfide is CH 3 –S–CH 3. Polyphenylene sulfide (see below) has the empirical formula C 6 H 4 S. Occasionally, the term sulfide refers to molecules containing the –SH functional group.
Some sulfides are named by modifying the common name for the corresponding ether. For example, C 6 H 5 SCH 3 is methyl phenyl sulfide, but is more commonly called thioanisole, since its structure is related to that for anisole, C 6 H 5 OCH 3. The modern systematic nomenclature in chemistry for the trival name thioether is sulfane. [2]

The compound (C 5 H 5) 2 TiS 5 is an example of a polysulfide complex. Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. [1] There are two main classes of polysulfides: inorganic and organic. The inorganic polysulfides have the general formula S 2− n. These anions are the conjugate bases of ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
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 ...
Dimethyl sulfide has a characteristic odor commonly described as cabbage-like.It becomes highly disagreeable at even quite low concentrations. Some reports claim that DMS has a low olfactory threshold that varies from 0.02 to 0.1 ppm [clarification needed] between different persons, but it has been suggested that the odor attributed to dimethyl sulfide may in fact be due to disulfides ...
