Options:
Answer:
B
Solution:
(P) [(H₂O)₄Fe(OH)(NH₂)Fe(H₂O)₄](SO₄)₂
- This is a binuclear complex with bridging ligands (OH⁻ and NH₂⁻).
- Only 2 ligands act as bridging ligands.
- Metal shows oxidation state ≥ +2.
- So matches: (2), (3).
(Q) [Co(NH₃)₅Cl]₃[Cr(ox)₃]₂
- Contains ionic complex salt → shows high electrical conductivity.
- Cr(ox)₃ is a stable anionic complex.
- Metal oxidation states satisfy ≥ +2 condition.
- So matches: (3), (4), (5).
(R) K₂[Cr(CN)₂O₂(O₂)NH₃]
- Contains mixed ligands including O₂ → synergic bonding possible.
- Cr is in stable oxidation state ≥ +2.
- So matches: (1), (3).
(S) H[AuCl₄]
- Anionic part [AuCl4]−[AuCl₄]⁻[AuCl4]− is homoleptic in nature (only Cl ligands).
- Au shows oxidation state ≥ +2.
- Also fits conductivity/acidic salt behavior.
- So matches: (3), (5).
