-1

Two complexes [Cr(H₂O)₆]Cl₃ (A) and [Cr(NH₃)₆]Cl₃ (B) are violet and yellow coloured, respectively. The incorrect statement regarding them is :

$$\Delta $$₀ values of (A) and (B) are calculated from the energies of violet and yellow light, respectively

both are paramagnetic with three unpaired electrons

both absorb energies corresponding to their complementry colors.

$$\Delta $$₀ value for (A) is less than that of (B).
