Question

Homoleptic complex from the following complexes is ______.

Options

• Potassium trioxalatoaluminate (III)

• Diamminechloridonitrito-N-platinum (II)

• Pentaamminecarbonatocobalt (III) chloride

• Triamminetriaquachromium (III) chloride

Answer 1

Homoleptic complex from the following complexes is Potassium trioxalatoaluminate (III).

Explanation:

• A homoleptic complex has all ligands identical.
• Potassium trioxalatoaluminate (III) contains three identical oxalate ligands bound to Al(III), so it is homoleptic.
• The other choices contain two or more different ligands (e.g., ammine + chloride + nitrito; ammine + carbonate; ammine + aqua), so they are heteroleptic.
