The following order is observed in the spectrochemical series for the ligands: CN- > NO2- > en > NH3 > H2O > C2O42- > OH- > F- > Cl- > Br- > I- Cr(CN) 63- and Co(CN) 63- are both negatively charged coordination complexes. Which statement describes the magnetic properties of the complexes?
A) Cr(CN) 63- and Co(CN) 63- are both diamagnetic.
B) Cr(CN) 63- is diamagnetic while Co(CN) 63- is paramagnetic.
C) Cr(CN) 63- is paramagnetic while Co(CN) 63- is diamagnetic.
D) Both complex ions are paramagnetic, but Cr(CN) 63- has a larger number of unpaired electrons than Co(CN) 63- hence its paramagnetism is more pronounced.
E) Both complex ions are paramagnetic, but Co(CN) 63- has a larger number of unpaired electrons than (CN) 63- hence its paramagnetism is less pronounced.
