1. Academic Chemistry Nomenclature

2. Naming Compounds  When naming compounds it is essential that you identify the kind of compound you are naming.  Why?  Naming rules vary with the type of compound. 2

3. Naming Compounds  There are 5 possible choices when naming compounds:  Binary Ionic Compound  Between a metal and a nonmetal  Ends in –ide  Ternary Ionic Compound  Has at least 3 elements (i.e. contains a polyatomic ion)  Usually ends in –ate or -ite 3

4. Naming Compounds  Binary Molecular Compound  Between a nonmetal and a nonmetal  Uses prefixes  Ends in –ide  Acids  Contain hydrogen  Hydro---ic means a binary acid  -ic means the oxyanion ends in –ate  -ous means the oxyanion ends in -ite 4

5. Naming Compounds  Bases  Contain hydroxide ions – OH -  Named like any ternary ionic compound 5

6. Naming Compounds  All binary compounds end in –ide. However there are 2 polyatomic that also end in –ide. You need to stay on the lookout for these:  OH - hydroxide  CN - cyanide 6
