Which of the following IUPAC names represents a homoleptic complex?
Options
- ATetraamminechloridonitrito-N-cobalt(III) chloride
- BDiamminedichloridoplatinum(II)
- CTris(ethane-1,2-diamine)cobalt(III) sulphate
- DPentaamminecarbonatocobalt(III) chloride
Correct answer
C. Tris(ethane-1,2-diamine)cobalt(III) sulphate
Step-by-step solution
A homoleptic complex is one in which the central metal atom or ion is bound to only one kind of donor group (ligand). Tris(ethane-1,2-diamine)cobalt(III) sulphate contains only one type of ligand, which is ethane-1,2-diamine (a bidentate ligand). Since all the ligands attached to the cobalt ion are identical, it is a homoleptic complex. The other options list complexes that contain more than one type of ligand (e.g., ammine along with chlorido, nitrito, or carbonato ligands). These are classified as heteroleptic co
