Jahn-Teller effect is not observed in high spin complexes of

Options

  1. Ad 7
  2. Bd 8
  3. Cd 4
  4. Dd 9

Correct answer

B. d 8

Step-by-step solution

Jahn Teller effect (JTE) explains the axial distortion in perfect octahedral geometry. It is present in d 4 high spin, d 7 low spin and d 9 configuration, which have an odd number of electrons in a e g set. A weak Jahn Teller effect is also present in d 7 high spin complex, which has an odd number of electrons in the set. Therefore, the Jahn Teller effect is not observed in high spin complexes of d 8 orbital.
