Statement-1: Among the complexes [Fe(CN)_(6)]^(4-)" and "[Fe(NH_(3))_(6)]^(2+), former complex absorbs the light of shorter wavelength. Statement-2: The crystal field splitting depends upon the strength of the ligands and charge on the metal ion.

Answer»

Statement-1 is True, Statement-2 is True , Statement-2 is a correct EXPLANATION for Statement-1.
Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.
Statement-1 is True, Statement-2 is FALSE.
Statement-1 is False, Statement-2 is True.

Solution :STRENGTH of ligand field as `CN^(-) gt NH_(3)`
`Delta_(0)` for `CN^(-)` complex `gt` `NH_(3)` complex. `Delta_(0)prop1/(lamda_(ABS))`
