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: • Li. Cl • Mg. I 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 • Fe. O • Cr. Cl 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) Hydroxide Potassium Nitrate Hydrogen Sulfide Rb. OH Li 2 SO 4 HNO 3 Na 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!!!! USE A PREFIX!!! EVERRR!! • Type C: (No polyatomics!!) two nonmetals only!! – MUST use a PREFIX, ONLY with two nonmetals!!
