The correct IUPAC name of potassium permanganate is:
Options:
Answer:
D
Solution:
The IUPAC name for KMnO₄ involves identifying the cation (potassium) and the polyatomic anion (permanganate, MnO₄⁻) and determining the oxidation state of manganese.
Concepts:
1. Nomenclature of ionic compounds.
2. Nomenclature of polyatomic ions.
3. Determining oxidation states.
The permanganate ion (MnO₄⁻) contains manganese in the +7 oxidation state. The prefix "tetraoxo" indicates four oxygen atoms, and "manganate(VII)" specifies manganese in the +7 oxidation state.
Therefore, the correct IUPAC name is Potassium tetraoxidomanganate(VII).
