Coordination Compounds question

2019 · 9 Jan · Shift 1 · Q14

JEE MainChemistryCoordination CompoundsMCQ+4 / −1
Two complexes [Cr(H2O)6]Cl3[Cr(H_2O)_6]Cl_3[Cr(H2​O)6​]Cl3​ (A) and [Cr(NH3)6]Cl3[Cr(NH_3)_6]Cl_3[Cr(NH3​)6​]Cl3​ (B) are violet and yellow coloured, respectively. The incorrect statement regarding them is :
  1. A
    Δ\DeltaΔ 0 values of (A) and (B) are calculated from the energies of violet and yellow light, respectively
  2. B
    both are paramagnetic with three unpaired electrons
  3. C
    both absorb energies corresponding to their complementry colors.
  4. D
    Δ\DeltaΔ 0 value for (A) is less than that of (B).
