Question

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. [Cr (OH2) 6] Cl3 reflects light in the wavelength range of about 4000-4200 angstroms.

B. The Δo calculated for [Cr (OH2) 6] 3+ is smaller than the Δo value calculated for [Cr (NH3) 6] 3+.

C. Since both chromium metal ions carry 3 unpaired electrons, they show paramagnetic properties.

D. For [Cr (NH3) 6] 3+, Δo is calculated by directly using the energy of yellow light.
