Chemistry Organic Building Blocks Sulfides
Organic sulfides, also known as thioethers, are functional groups in organic chemistry that have the connectivity R−S−R'. Volatile sulfides often possess unpleasant odors, similar to many other sulfur-containing compounds.
In organic chemistry, a sulfide is a functional group that resembles an ether but has a sulfur atom instead of an oxygen atom in its structure. The close proximity of oxygen and sulfur in the periodic table implies that ethers and sulfides may exhibit similar chemical properties, although this can vary depending on the specific use case.
Their physical properties are similar to ethers, but they have some differences. Sulfides have higher melting points and are less volatile than ethers, and they are also less hydrophilic. The reason for these differences is that the divalent sulfur atom in sulfides is more polarizable than the oxygen atom in ethers.
Organic sulfides are prone to catch fire easily and are highly flammable. During combustion, sulfides emit sulfur dioxide (SO2) gas.
Thioether is a more specific term than sulfide in organic chemistry, referring to any organic compound containing a C–S–C linkage.
