Thioether functional group
WebThioether functional groups possess similar boiling points and solubility features, well this does not hold true for alcohols. Volatile thiols can be easily identified due to their distinctive odours. Reactions of Thiol Many reactions are exhibited by thiols similar to that of hydroxyl compounds involving the formation of sulphides and thioesters. WebThio ether (sulfide): A functional group characterized by a sulfur atom flanked by two carbon atoms of any hybridization . These carbons cannot be carbonyl carbons. Related terms: Sulfhydryl group, ether , thiol , mercaptan , thioester , thiolester , sulfoxide , sulfone , sulfonic acid, sulfonamide , sulfonyl chloride, disulfide
