Question

Homoleptic complex from the following complex is ____.

Options

• Diamminechloridonitito - N - platinum (II)

• Pentaamminecarbonatocobalt (III) chloride

• Triamminetriaquachromium (III) chloride

• Potassium trioxalatoaluminate (III)

Answer 1

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

Explanation:

We can write the formula for all the compounds.

[Pt(NH₃)₂CI(NO₂)]

[Co(NH₃)₅(CO₃)]Cl

[Cr(NH₃)₃(H₂O)₃]C1₃

K[AI(C₂O₄)₃]

Since, option 4 contain all ligands are of same type i.e. why complex will be homoleptic.
