MCQ
Which of the following cannot be explained by crystal field theory?
  • A
    The order of spectrochemical series
  • B
    Magnetic properties of transition metal complexes
  • C
    Colour of metal complexes
  • ✓
    Stability of metal complexes
✓

Answer

Correct option: D.
Stability of metal complexes
d
Crystal field theory introduce spectrochemical series based upon the experimental values of $\Delta$ but can't explain it's order. While other three points are explained by $CFT$. Specially when the $CFSE$ increases thermodynamic stability of the complex increases.
