  1. Naming Binary Molecular Compounds

  2. Binary Molecular Compounds • Compounds between two nonmetals • First element in the formula is named first. • Keeps its element name • Gets a prefix if there is a subscript on it • Second element is named second • Use the root of the element name plus the -idesuffix • Always use a prefix on the second element

  3. List of Prefixes • 1 = mon(o) • 2 = di • 3 = tri • 4 = tetra • 5 = penta • 6 = hexa • 7 = hepta • 8 = octa • 9 = nona • 10 = deka

  4. Naming Binary Compounds P2O5= diphosphoruspentoxide CO2 = carbon dioxide CO = carbon monoxide N2O = dinitrogenmonoxide
