Two complexes `[Cr(H_(2)O_(6))_(6)]Cl_(3)` and `[Cr(NH_(3))_(6)]Cl_(3)` (B) are violet and yellow coloured, respectively. The incorrect statement regarding them is :

Options

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

Answer

C

Explanation

Both the complexes contain Cr in +3 O.S so they are both paramagnetic with 3 unpaired electrons each. `-H_(2)O` is a weak field ligand and as compared to `NH_(3)` so `Delta_(0)` for A is less than B.
