CHEM 1150 Fall 2014 Nomenclature Part I: Naming Ionic Compounds
1.
2.
Metals that form one ion
Types:
+1 cation
Group one
□
Silver
□
H
Often called a proton
®
□
§
+2 cation
Group 2
□
Zinc
□
Cadmium (Cd2+)
□
§
+3 cation
Aluminum
□
§
-1 Anion
Group 7 (F, Cl, Br, I)
□
H- = hydride
□
§
-2 anion , in this class only responsible for
O2- oxide
□
S2- sulfide
□
§
-3 only responsible for
N3- nitride
□
§
○
Rules for naming:
Name of cation (metal)
§
Base name of anion (non-metal) +-ide
§
Ex. KCl=Potassium Chloride
CaBr2= Calcium Bromide
□
Ag3N= Silver Nitride□
§
○
3. Metals w/ multiple oxidations (transition metals)
Rules for naming:
Name of cation (metal)
§
Charge of metal in roman numerals in parentheses
§
Base name of anion (non-metal) + -ide
§
Ex. CuO= Copper (II) Oxide
FeCl3= Iron (IV) Chloride□
FeCl2= Iron (II) Chloride□
§
○
4. Common monoatomic and polyatomic ions
Polyatomic b/c formed w/ non-metals (covalent bonds), nom-neutral
○
Recognize that [Polyatomic anions made up of non-metals and also
made up of Oxygens so called oxyanions
w/ oxyanions
§
○
Polyatomic compound cation followed by anion
FeSO4 = Iron (II) Sulfate
§
NH4NO3= Ammonium Nitrate
§
○
Hydrated Ionic Compounds
CaSO4 (dot) 1/2 H2O = Calcium Sulfate hemihydrate
§
BaCl2 (dot) 6 H2O = Barium Chloride hexahydrate
§
○
CHEM 1150 Fall 2014 Nomenclature Part II: Naming Molecular Compounds5.
Predominately covalent bonds so share electrons
Rule:
Prefix (except mono)
§
Name of 1st element
§
Prefix
§
Base name of 2nd element + -ide
§
w/ 2 vowels back 2 back (like oxide) drop first (ex. Pentaoxide is
just pentoxide)
§
Ex. P2O5= diphosphorus pentoxide
§
○
WATER IS DIHYDROGEN MONOXIDE
○
-
CHEM 1150 Fall 2014 Nomenclature Part III: Naming Acids6.
Binary acids (two-elements) (group 7 non-metals)
Rule:
Hydro
§
Base name of non-metal + -ic
§
Acid
§
Ex. HCl= Hydrochloric acid
§
○
-
Oxy-acids (contain oxygens)
2 types
Ending in -ate
Rule
Base name of oxyanion + -ic
®
Acid
®
□
Ex. H2SO4 = sulfuric acid□
§
Remember: I ate something icky
§
Ending in -ite
Rule
Base name of oxyanion + -ous
®
Acid
®
□
Ex. H2SO3= sulfurous acid□
