Which is the incorrect observation?

  • A
    For the complex,$[CoF_6]^{3-}$,$F^{-}$ is a weak-field ligand,so that $\Delta_{oct} < P$ (electron-pairing energy) and is thus a high spin complex.
  • B
    For the complex,$[Co(NH_3)_6]^{3+}$,$NH_3$ is a strong-field ligand,so that $\Delta_{oct} > P$ and thus a low spin complex.
  • C
    Stability order: $[Co(H_2O)_6]^{3+} > [Rh(H_2O)_6]^{3+}$
  • D
    Greater the ionic charge on the central metal ion,the greater the value of $\Delta$ $(CFSE)$.
