MCQ
IUPAC name for the complex [Cu(NH3)4]SO4 is:
- ACupramonium sulphate.
- BCopper sulphate tetraamonia.
- CTetrammine copper (II) sulphate.
- DCopper amonium (IV) sulphate.
✓
Answer
- Tetrammine copper (II) sulphate.
Explanation:
Since 4 amino groups are present, it will be called as tetrammine.
Since copper(II) is the central metal, it will be tetrammine copper(II). Note that we can determine the oxidation number of copper by charge balance.
Now finally since sulphate is the counter ion, it's full name will be tetrammine copper(II) sulphate.
