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 MgI 2 Na 2 O 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: Fe 2 O 3 FeO CrCl 2 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: CO 2 CO N 2 O 3 CCl 4 And, yes let’s go backwards one last time Sulfur Dioxide Trinitrogen Hexaoxide Oxygen Dichloride

Nomenclature Practice: – Chromium (III) Chloride – Li 2 O – Rubidium Oxide – Dihydrogen Monoxide – Trinitrogen Hexaoxide – Iron (II) Fluoride

Polyatomics Same 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) HydroxideRbOH Potassium NitrateLi 2 SO 4 Hydrogen SulfateHNO 3 Hydrogen SulfideNa 3 PO 4

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: (No polyatomics!!)  two nonmetals only!! – MUST use a PREFIX, ONLY with two nonmetals!!
