Contrary to biology, biochemistry and biomedicine branches, in organic and inorganic chemistry branches, and in the branche of chemical nomenclature (see IUPAC), the correct name for the group is not "phosphoryl", but phosphonato, and the correct name for the group is phosphono, and the term phosphoryl correctly refers to the trivalent >P(=O)− group.https://www.ebi.ac.uk/chebi/ Example of molecules containing that trivalent phosphoryl group are phosphoryl chloride (), methylphosphonyl dichloride () and phosphoramide ().
