Considering that [Cr (OH2) 6] Cl3 compound is purple, [Cr (NH3) 6] Cl3 compound is yellow, which of the following statements is wrong according to the Crystal Field Theory about these compounds? (24Cr) (Use the color circle given in the figure) A. Since both chromium metal ions carry 3 unpaired electrons, they show paramagnetic properties. B. The Δo calculated for [Cr (OH2) 6] 3+ is smaller than the Δo value calculated for [Cr (NH3) 6] 3+. C. [Cr (OH2) 6] Cl3 reflects light in the wavelength range of about 4000-4200 angstroms. D. For [Cr (NH3) 6] 3+, Δo is calculated by directly using the energy of yellow light.
