Nomenclature Chemistry Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
Name the following ionic compounds: (a) NaCl, (b) CaO\text{CaO}, (c) FeCl3\text{FeCl}_3.

Solution

  1. 1
    (a) Na = sodium, Cl = chloride → sodium chloride.
  2. 2
    (b) Ca = calcium, O = oxide → calcium oxide.
  3. 3
    (c) Fe can have multiple charges. With 3 Cl−^-, Fe must be +3+3. → iron(III) chloride.

Answer

(a) sodium chloride, (b) calcium oxide, (c) iron(III) chloride\text{(a) sodium chloride, (b) calcium oxide, (c) iron(III) chloride}
For ionic compounds, name the cation first and then the anion (with -ide ending). Transition metals require Roman numerals to indicate their charge since they can form multiple ions.

About Nomenclature

The systematic method for naming chemical compounds according to IUPAC (International Union of Pure and Applied Chemistry) rules, ensuring that every compound has exactly one.
