NEET (UG) 2023 — Question 56

Homoleptic complex from the following complexes is :

  1. Option A:

    Diamminechloridonitrito - N platinum (II)

  2. Option B:

    Pentaamminecarbonatocobalt (III) chloride

  3. Option C:

    Triamminetriaquachromium (III) chloride

  4. Option D:

    Potassium trioxalatoaluminate (III)

    Correct

Answer: D

Step-by-step solution

A homoleptic complex has only one type of ligand. Option A: [Pt(NHX3)(Cl)(NOX2)]\ce{[Pt(NH3)(Cl)(NO2)]} contains three different ligands (ammine, chlorido, nitrito-N) → heteroleptic. Option B: [Co(NHX3)X5(COX3)]Cl\ce{[Co(NH3)5(CO3)]Cl} contains two different ligands (ammine, carbonate) → heteroleptic. Option C: [Cr(NHX3)X3(HX2O)X3]ClX3\ce{[Cr(NH3)3(H2O)3]Cl3} contains two different ligands (ammine, aqua) → heteroleptic. Option D: KX3[Al(ox)X3]\ce{K3[Al(ox)3]} contains only oxalate ligands → homoleptic. Thus, the correct answer is D.
