The following order is observed in the spectrochemical series for ligands CN- > NO2- > en > NH3 > H2O > C2O42- > OH- > F- > Cl- > Br- > I-Cr(NH3) 63+ and Ni(NH3) 62+ are both positively charged coordination complexes. Which statement describes the magnetic properties of the complexes?
A) Cr(NH3) 63+ and Ni(NH3) 62+ are both diamagnetic.
B) Cr(NH3) 63+ is diamagnetic while Ni(NH3) 62+ is paramagnetic.
C) Cr(NH3) 63+ is paramagnetic while Ni(NH3) 62+ is diamagnetic.
D) Both complex ions are paramagnetic, but Cr(NH3) 63+ has a larger number of unpaired electrons than Ni(NH3) 62+ hence its paramagnetism is more pronounced.
E) Both complex ions are paramagnetic, but Ni(NH3) 62+ has a larger number of unpaired electrons than Cr(NH3) 63+ hence its paramagnetism is more pronounced.
