1.	The d-orbitals participating in hybridisation of metal atom may be from the n & (n-1) shell. This depends on the nature of metal and nature of ligand. The complexes involving the inner d-level (inner orbital complexes) results when the ligand is a powerful (or) strong ligand results in a diamagnetic (or) low spin complexes. A weak ligand usually results in the formation of outer orbital complex (or) high spin complex. Number of unpaired electrons present in [Fe(CN)_(6)]^(4-)&[Fe(H_(2)O)_(6)]^(2+) are respectively.
Answer» 4,4 0,0 0,4 2,4 Solution :`CN^(-)` : Strong field ligand and electronic rearrangment is POSSIBLE `H_(2)O` weak field ligand and no ELECTRIC rearrangement. (in presence of `H_(2)O)` ) (in presence of `CN^(-)` )
