QJEEM20Ch8c48: JEE Main 2020 Chemistry - Class 12 JEEM20Ch8c48 Solution: The values of the crystal field stabilization energies for a…
The values of the crystal field stabilization energies for a high spin d6 metal ion in octahedral and tetrahedral fields, respectively, are :
Multiple Choice Options
- A –0.4 0 and –0.27 t
- B –1.6 0 and –0.4 t
- C –0.4 0 and –0.6 t
- D –2.4 0 and –0.27 t
Step-by-Step Verified Solution
In octahedral 
CFSE = [-0.4nt2g + 0.6neg] 0
= [-0.4 4 + 0.6 2] 0
= -0.4 0
In tetrahedral fields
CFSE = [-0.6neg + 0.4nt2g] t
= (– 0.6 × 3 + 0.4 × 3) t
= (–1.8 + 1.2) t
= –0.6 t
CFSE = [-0.4nt2g + 0.6neg] 0
= [-0.4 4 + 0.6 2] 0
= -0.4 0
In tetrahedral fields
CFSE = [-0.6neg + 0.4nt2g] t
= (– 0.6 × 3 + 0.4 × 3) t
= (–1.8 + 1.2) t
= –0.6 t
