MHT CET 2026 Chemistry question
Which of the following comparisons is correct for of the following complexes?
I - [Co(HO)]
II - [Co(HO)]
III - [Fe(HO)]
IV - [Fe(CN)]
Answer: (A)
Solution
The crystal field splitting depends on the ligand and on the metal ion; for the same ligand and the same metal, increases with the oxidation state because the higher charge pulls the ligands closer. Complexes I and II both contain Co and HO, with Co in +2 and +3 states, so of
