Q14 / 214 · NTA Abhyas (NEET) 2020 · Chemistry · Coordination Compounds

In the spectrochemical series, the magnitude of the crystal field splitting is maximum for which ion?

  • A
    Cl-
  • B
    F-
  • C
    NO2
  • Correct answer
    D
    CN-

Solution

CN- ion is at the extreme right but before CO in the spectrochemical series. So, it can cause maximum splitting of d-orbitals.
C-N>NO2->F->Cl-

Hence, the correct answer is option: 'D'.
