A thioether (similar to sulfide)'s a functional group in organic chemistry that's the structure R1-S-R2 as shown on right. Like many other sulfur-containing compounds, volatile thioethers characteristically have foul odors. A thioether's similar to an ether except that it contains a sulfur atom in place of the oxygen. Because oxygen and sulfur belong to the chalcogens group in the periodic table, the chemical properties of ethers and thioethers are somewhat similar. This functional group's impor… (More on Thioether)
