CoF 6 3 - absorbs light in the red region of the spectrum, while Co(NH 3 ) 6 3+ absorbs light in the blue region of the spectrum. This difference means that ________

The crystal field splitting is larger for the ammonia complex than for the fluoride complex because Co(NH₃)₆³⁺ absorbs higher energy (blue) light, indicating a larger splitting compared to CoF₆³⁻, which absorbs lower energy (red) light.

Solved

CoF₆³^- Absorbs Light in the Red Region of the Spectrum

Question 62

Multiple Choice

CoF₆³^- absorbs light in the red region of the spectrum, while Co(NH₃) ₆³⁺ absorbs light in 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 CoF₆³^- 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 CoF₆³^- and just the opposite splitting order for Co(NH₃) ₆³⁺.
