Nomenclature for Binary Compounds I Ionic II Ionic III Covalent
Covalent Compounds • Covalent cmps have covalent bonds involving electron sharing • Covalent bonds form between two non metals. • Type III: name more cation-like first; use prefixes to identify number of each atom.
Ionic Compounds (IC) • IC have ionic bonds due to transfer of electrons and then attraction of oppositely charged ions. • IC are cmps containing a metal (+; name first) and a non metal (-, name second with –ide ending), or a polyatomic ion. • Type I: IC whose cation has a single common charge state. IC must be neutral. • Type II: IC whose cation has more than one common charge state. Use (RN) to identify charge state. IC must be neutral
Type I • Magnesium oxide MgO • CaF2 calcium fluoride • Na2S sodium sulfide • Potassium bromide KBr • BaS barium sulfide • Sodium sulfite Na2SO3 • (NH4)2SO4 aluminum sulfate • Aluminum oxide Al2O3
Type II • Copper(II) chloride CuCl2 • Fe2O3 iron(III) oxide • Mn(II) oxide MnO • Chromium(II) phosphide Cr3P2 • SnCl4 tin(IV) chloride • Cobalt(III) sulfate Co2 (SO4)3 • Mn2O3 manganese(III) oxide • Calcium hydrogen carbonate Ca(HCO3)2
Type III • Nitrogen tribromide NBr3 • P4O10 tetraphosphorus decoxide • Oxygen difluoride OF2 • Fe2O3 iron(III) oxide • Dichlorine pentoxide Cl2O5 • N2F2 dinitrogen difluoride
