The homoleptic complex from the following complexes is:
Answer: (A) Potassium trioxalatoaluminate(III). \textbf{Answer:} (A) Potassium trioxalatoaluminate(III).
- A.Potassium trioxalatoaluminate(III)✓
- B.Diamminechloridonitrito-N-platinum(II)
- C.Pentaamminecarbonatocobalt(III) chloride
- D.Triamminetriaquachromium(III) chloride
Correct Answer
(A) Potassium trioxalatoaluminate(III)
Solution & Explanation
\textbf{Answer:} (A) Potassium trioxalatoaluminate(III). \textbf{Solution:} A homoleptic complex contains only one kind of ligand bound to the metal; a heteroleptic complex contains more than one kind. Parsing each name into its coordination sphere: Potassium trioxalatoaluminate(III) = — only oxalate ligands → homoleptic. Diamminechloridonitrito-N-platinum(II) = — ammine, chlorido and nitrito ligands → heteroleptic. Pentaamminecarbonatocobalt(III) chloride = — ammine and carbonato → heteroleptic. Triamminetriaquachromium(III) chloride = — ammine and aqua → heteroleptic. Only has a single type of ligand, so the homoleptic complex is option (A).
