Which of the following will have maximum stabilization due to crystal field?

Question

Canvas Classes · Accepted Answer

Strategy:
 Compare the Crystal Field Stabilization Energy (CFSE) magnitude for the given complexes. Larger  and specific d-electron tracking (low spin) yield higher stabilization.

Step 1: Calculate CFSE estimates
- :  () .
- :  ( high-spin) .
- :  () with strong field   low-spin . This has both the highest multiplier  and the largest inherent  due to  and .
- : Square planar/tetrahedral, generally much lower absolute splitting stabilization than a  low-spin octahedral.

has the maximum CFSE.
