MCQ
Which of the following complexes is not a chelate?
- Abis(dimethylglyoximato)nickel $(II)$
- Bpotassium ethylenediaminetetrathiocyanatochromate $(III)$
- ✓tetraamminediazidocobalt $(III)$ nitrate
- Dtrans-diglycinatoplatinum $(II)$
✓
Answer
Correct option: C.
tetraamminediazidocobalt $(III)$ nitrate
c
The complex Tetrammine carbonatocobalt $(III)$ nitrate is the only option in which the the ligands (ammine and cabonato) are monodentate and hence it does not form a chelate on the other hand rest all complexes have polydentate ligands.
