Options
- A(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
- B(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- C(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- D(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
Correct answer
A. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
Step-by-step solution
Homoleptic complexes contain only one type of ligand, while heteroleptic complexes contain more than one type of ligand. (A) [Co(NH₃)₄Cl₂]^+ contains two types of ligands ( NH₃ and Cl^- ), so it is heteroleptic. It carries a positive charge, making it cationic. (Matches IV) (B) K₃[Fe(CN)₆] contains only one type of ligand ( CN^- ), so it is homoleptic. The coordination entity is [Fe(CN)₆]³⁻ , which is anionic. (Matches I) (C) [Ni(CO)₄] contains only one type of ligand ( CO ), so it is homoleptic. It carries no char
