CoF63-absorbs light in the red region of the spectrum, whereas Co(NH3) 63+0 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 dz2 and
orbitals are higher in energy than the dxy, dxz, and dyz orbitals in CoF63- and just the opposite splitting order for Co(NH3) 63-.
E) the dz2 and dx2-y2 orbitals are lower in energy than the dxy, dxz, and dyz orbitals in CoF63- and just the opposite splitting order for Co(NH3) 63-.
