1. Nomenclature and Mixtures
Naming Compounds
IUPAC NAMING

2. Nomenclature
Naming Chemical Compounds
Three Types:

3. Nomenclature
Type A: Ionic
Metals with known charge + Nonmetals

4. 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)

5. Nomenclature
Type B: Ionic
Metals with UNKNOWN charge + Nonmetals

6. 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

7. Nomenclature
Type C: COVALENT
Nonmetal + Nonmetal

8. 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

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

10. 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

11. 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!!
