CoF₆^3- Absorbs Light in the Red Region of the Spectrum,whereas

question 125

Multiple Choice

CoF₆^3- absorbs light in the red region of the spectrum,whereas Co(NH₃) ₆³⁺ absorbs light on the blue region of the spectrum.This difference means that __________

• A)the splitting of the d orbitals of the two complexes is nearly identical.
• B)the value of the crystal field splitting is very small for both complexes.
• C)the crystal field splitting is larger for the ammonia complex than for the fluoride complex.
• D)the d_z² and d_x²_-y² orbitals are higher in energy than the d_xy,d_xz,and d_yz orbitals in CoF₆^3- and just the opposite splitting order for Co(NH₃)₆³⁺.
• E)the d_z² and d_x²_-y² orbitals are lower in energy than the d_xy,d_xz,and d_yz orbitals in CoF₆^3- and just the opposite splitting order for Co(NH₃)₆³⁺.
