Question

What are the IUPAC names of the following compounds? 

1. Manganese dioxide
2. Mercurous chloride (Hg₂Cl₂)
3.  Ferric nitrate [Fe(NO₃)₃]
4. Titanium Tetrachloride
5.  Cupric bromide (CuBr₂)

Step-by-Step Solution

Answer

1. The IUPAC name of manganese dioxide is Manganese(iv)oxide.
2.  The IUPAC name of mercurous chloride is chloromercury. Or Mercury(I) chloride
3. The IUPAC name of ferric nitrate is iron(III)nitrate.
4. The IUPAC name of Titanium Tetrachloride is titanium(IV) chloride.

      5.The IUPAC name of Cupric bromide is copper(II)bromide.

Step 1: Follow the rules of naming the compounds

• If the compound is a salt, cation is named first then anion is named.
• A Roman number is added in the bracket to specify the oxidation state of metal.
• If the metal is anionic complex ion, use the suffix -ate.
• Ligand is named before the central metal atom.
• If more than one ligand is there, they are named in alphabetical order.

Step 2: Determine the IUPAC names

1. The IUPAC name of manganese   dioxide is Manganese(iv)oxide.
2. The IUPAC name of mercurous chloride is chloromercury. Or Mercury(I) chloride
3. The IUPAC name of ferric nitrate is iron(III)nitrate.
4. The IUPAC name of Titanium Tetrachloride is titanium(IV) chloride.
5. The IUPAC name of Cupric bromide is copper(II)bromide.
