JEE Main 2022 Chemistry question
Consider the following metal complexes: The spin-only magnetic moment value of the complex that absorbs light with shortest wavelength is B.M. (Nearest integer)
Answer: 0
Solution
In all the complexes cobalt is in the +3 state and all are low-spin (inner orbital) complexes. A stronger ligand gives larger crystal field splitting, so the order of splitting is $ > >
