Solution:
- Key Idea Crystal field splitting occurs due to the presence of ligands in a definite geometry. In octahedral complexes the energy of two,
orbitals will increase by and that of three will decrease by .
The complex ion that will lose its crystal field stabilisation energy upon oxidation of its metal to +3 state is
In
CFSE
The splitting of orbital and arrangement of electrons in
CFSE
