# Solve this following

Question:

Two complexes $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}_{6}\right) \mathrm{Cl}_{3}\right]$ (A) and $\left[\mathrm{Cr}\left(\mathrm{NH}_{3}\right)_{6}\right] \mathrm{Cl}_{3}(\mathrm{~B})$ are violet and yellow coloured, respectively. The incorrect statement regarding them is :

1. $\Delta_{0}$ value of $(\mathrm{A})$ is less than that of $(\mathrm{B})$.

2. $\Delta_{0}$ value of (A) and (B) are calculated from the energies of violet and yellow light, respectively

3. Bothe absorb energies corresponding to their complementary colors.

4. Bothe are paramagnetic with three unpaired electrons.
