They may be symmetrical or mixed, which affects the complexity of their nomenclature, and their oxygen atom may be replaced by sulfur, in which case the molecule may be given the designation "sulfane." Consisting of two carbonyl groups with only an oxygen between them, the acetic type is a quite common reagent that is created when two molecules of acetic acid come together and kick off water. FTP, name this functional group with a name that literally means "without water."
