CEM 141 Lecture Notes - Nsb Di 3, Bicarbonate, Oxyanion
Document Summary
Note the ide ending for cyanide and hydroxide. This ending is usually reserved for simple monatomic anions (like chloride, cl -). Cyanide and hydroxide are exceptions to this rule. For hydrogen carbonate and hydrogen sulfate note that h+ has been added to a -2 oxyanion, reducing the charge by one. Older nomenclature uses the prefix "bi" in place of "hydrogen". Nonmetals can combine with other nonmetals to make covalent compounds. Because nonmetals can share elec- trons in covalent bonds in many different ways, it is necessary to specify the number of each element in the compound. The prefixes tell how many oxygens are combined with carbon in the covalent com- pound. Here is a list of the prefixes used in covalent nomenclature: Prefix mono (not used for the first element in the compound) Binary covalent compounds always end in ide: carbon monoxide, carbon dioxide.
