Chapter 4
Naming Binary and Complex Compounds
1. To learn to name binary compounds of a metal and nonmetal
2. To learn to name binary compounds containing only nonmetals
3. To summarize the naming of all types of binary compounds
Objectives
1. AxBy where A is a metal, B is a non-metal
2. CxDy where C and D are non-metals
Chapter 4
Naming Binary and Complex Compounds A. Naming Compounds That Contain a Metal and a
Nonmetal • Binary ionic compounds contain positive cations and
negative anions. – Type I compounds
• Metal present forms only one cation – Type II compounds
• Metal present can form 2 or more cations with different charges

Nonmetal
Chapter 4
Naming Binary and Complex Compounds A. Naming Compounds That Contain a Metal and a
Nonmetal • For compounds containing both a metal and a nonmetal,
the metal is always named first. The nonmetal is named from the root element name.

acid’s name 4. To learn names for common acids 5. To learn to write the formula for a compound, given its
name
Objectives
Chapter 4
Naming Binary and Complex Compounds
A. Naming Compounds That Contain Polyatomic Ions
• Polyatomic ions are charged entities composed of several atoms bound together (“charged molecules”).
• Compounds should be electrically neutral • Use parentheses (when appropriate) in writing formulas
e.g Ni(CN)2
• They should be considered as other ions in determining names of compounds
• They have special names which should be memorized.
Chapter 4
Naming Binary and Complex Compounds
A. Naming Compounds That Contain Polyatomic Ions
• Naming ionic compounds containing polyatomic ions follows rules similar to those for binary compounds. – ammonium acetate
Rules D

Chapter 4
Naming Binary and Complex Compounds
Acids You Should Know
• Hydrochloric Acid (HCl) – many industrial uses, stomach acid
• Sulfuric Acid (H2SO4) – major commercial chemical ~200 million Tons annually
• Nitric Acid (HNO3) – used to make fertilizers and explosives
• Acetic Acid (HC2H3O2) – vinegar • Carbonic Acid (H2CO3) – ocean acidification, sodas • Hydrofluoric Acid (HF) – etches glass, very toxic
