Nomenclature and Mixtures Naming Compounds IUPAC NAMING

Nomenclature Naming Chemical Compounds Three Types:

Nomenclature Type A: Ionic Metals with known charge + Nonmetals

Let’s Practice, Shall We?? Name the following using Type A rules: LiCl MgI2 Na2O Now go the other way: Beryllium Nitride Calcium Selenide Hydrogen Chloride (a.k.a. hydrochloric acid)

Nomenclature Type B: Ionic Metals with UNKNOWN charge + Nonmetals

Let’s Practice, Shall We?? Name the following using Type B rules: Fe2O3 FeO CrCl2 Now go the other way: Manganese (I) Bromide Nickel (II) Phosphide Cobalt (III) Selenide

Nomenclature Type C: COVALENT Nonmetal + Nonmetal

Let’s Practice, Shall We?? Name the following using Type C rules: CO2 CO N2O3 CCl4 And, yes let’s go backwards one last time Sulfur Dioxide Trinitrogen Hexaoxide Oxygen Dichloride

Nomenclature Practice: Chromium (III) Chloride Li2O Rubidium Oxide Dihydrogen Monoxide Trinitrogen Hexaoxide Iron (II) Fluoride

Polyatomics Sames rules apply Just cancel out the charges These use Type A and B rules, NOT Type C NEVER USE A PREFIX WITH POLYATOMICS!! Try: Iron (III) Hydroxide RbOH Potassium Nitrate Li2SO4 Hydrogen Sulfate HNO3 Hydrogen Sulfide Na3PO4

Nomenclature, IN A NUTSHELL Type A: (works with polyatomics too) Must know the charge Cancel the charges out and name it Add –ide to the end Type B: (works with polyatomics too) MUST use a Roman Numeral (tells us the charge) Then name just like “A” NEVER, EVER, EVER!!!! USE A PREFIX!!! EVERRR!! Type C: (a polyatomic is metal so they CANNOT be used here  two nonmetals only!! MUST use a PREFIX, ONLY with two nonmetals!!
