Two complexes [Cr(H 2 O) 6 ]Cl 3 (A) and [Cr(NH 3 ) 6 ]Cl 3 (B) are violet and yellow coloured, respectively. The incorrect statement regarding, them is -

1. Δ 0 value for (A) is less than that of (B).
2. both absorb energies corresponding to their complementary colors.
3. Δ 0 values of (A) and (B) are calculated. From the energies of violet and yellow light, respectively.
4. both are paramagnetic with three unpaired electrons.

Correct answer: Δ 0 values of (A) and (B) are calculated. From the energies of violet and yellow light, respectively.
