MCQ
Which of the following complexes is not a chelate?
  • A
    bis(dimethylglyoximato)nickel $(II)$
  • B
    potassium ethylenediaminetetrathiocyanatochromate $(III)$
  • ✓
    tetraamminediazidocobalt $(III)$ nitrate
  • D
    trans-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.
