Study Notes
IUPAC Chemical Nomenclature
- IUPAC stands for the International Union of Pure and Applied Chemistry
- It's an organization that sets standards for chemical nomenclature
- This presentation covers various types of chemical compounds and their naming conventions
Types of Chemical Compounds
- Covalent compounds
- Ionic compounds (binary)
- Ionic compounds (multivalent)
- Ionic compounds (polyatomic)
- Ionic compounds (hydrated)
- Binary acids
- Oxy-acids
- Simple organic compounds
- Elements
Binary Covalent Compounds
- Two atoms bonded with a difference in electronegativity less than 1.7
- No ions involved; no criss-crossing to find the formula
- Use prefixes to indicate the number of each atom
- The name ends in "-ide"
- Prefixes (e.g., mono-, di-, tri-, tetra-, penta-) indicate the number of atoms of each element in the compound
- The prefix "mono" is never used for the first element in the formula
Examples of Covalent Naming
- Write the names for SO2 and P4O10
- Write the formulas for phosphorus pentachloride and dinitrogen trioxide
Ionic Compounds - Binary
- Metal cations bond with non-metal anions
- Cations frequently have only one possible charge.
- Use a periodic table to predict charges for cations
- Simple anions use the suffix "-ide" (e.g., oxide, nitride, fluoride, bromide)
Ionic Compound Formulas
- Cation and anion charges must cancel out
- Criss-cross method can be used, but reduce if possible
- Example formulas: potassium iodide, lithium oxide, aluminum bromide, zinc nitride
Practice - Binary Ionic Compounds
- Give formulas for: potassium fluoride, sodium bromide, calcium chloride, magnesium sulfide, lithium nitride, and aluminum phosphide
Naming Ionic Compounds
- Name the metal cation first
- Name the nonmetal anion, change the ending to "-ide"
- No prefixes are used
Practice - Naming Ionic Compounds
- Name the following: NaCl, MgF2, K2S, AlBr3, CaO, Mg3N2
Ionic Compounds - Multivalent
- Some metal cations have multiple possible charges
- Use Roman numerals in parentheses after the metal name to indicate the charge (e.g., iron(II), iron(III))
- Older naming system uses suffixes (-ic for higher charge, -ous for lower charge)
Practice - Multivalent Compounds
- Give formulas for: iron(II) sulfide, copper(I) oxide, tin(IV) oxide, chromium(III) bromide, nickel(II) oxide, iron(III) sulfide
- Name the following: FeO, SnF4, PbO2, CoF3, Fe2O3, VF4
