Question

What are the names of the compounds that match the given chemical formulas?

1) manganese(ii) chloride
2) manganese(iv) chloride
3) manganese(ii) oxide
4) manganese(iv) oxide

Answer 1

The IUPAC names for the given chemical formulas are Manganese dichloride for manganese(II) chloride, Manganese(II) oxide for manganese(II) oxide, and Manganese dioxide for manganese(IV) oxide. Manganese(IV) chloride is not a stable compound with a recognized IUPAC name.

Step-by-step explanation:

The chemical formulas given can be matched with their corresponding International Union of Pure and Applied Chemistry (IUPAC) names as follows:

1. Manganese(II) chloride - The IUPAC name for MnCl₂ is Manganese dichloride.
   
2. Manganese(IV) chloride - MnCl₄ does not exist as a stable compound under normal conditions, and it does not have a widely recognized IUPAC name.
   
3. Manganese(II) oxide - The IUPAC name for MnO is Manganese(II) oxide.
   
4. Manganese(IV) oxide - The IUPAC name for MnO₂ is Manganese(IV) oxide, also known as Manganese dioxide.
