MCQ
Which is a coordination compund?
- AFerrous ammonium sulphate
- BCarnallite
- CPotassium ferrocyanide
- DGypsum
✓
Answer
- Potassium ferrocyanide
Explanation:
Only 'Potassium ferrocyanide' (i.e. [Fe(CN)5] ) shows properties of coordination compound.
When it gets dissolve they do not form simple ion like Fe+2 or CN−, but instead their complex ions remain intact.
whereas carnallite (i.e. KMgCl3 ), Gypsum (i.e. CaSO4) and Ferrous ammonium sulphate (i.e. (NH4)2Fe(SO4)2 ) they dissovle and give simple ions.
