# (Crystal Field Theory) Consider the violet-colored compound, $[Cr(OH_2)_6]Cl_3$ and the yellow compound, $[Cr(NH_3)_6]Cl_3$. Which of the following statements is false?

$\begin{array}{1 1}(a)\;\text{Both chromium metal ions are paramagnetic with 3 unpaired electrons}\\(b)\;￼ \Delta_{oct}\; for\; [Cr(NH_3)_6]^{3+}\;\text{is calculated directly from the energy of yellow light}\\(c)\; ￼ \Delta_{oct}\; for\; [Cr(OH_2)_6]^{3+}\;\text{is less than}\;￼ \Delta_{oct}\; for \;[Cr(NH_3)_6]^{3+}\\(d)\;\text{A solution of }[Cr(OH_2)_6]Cl_3\text{ transmits light with an approximate wavelength range of 4000 - 4200 angstroms}\end{array}$

$\Delta_{oct}\; for\; [Cr(NH_3)_6]^{3+}\;\text{is calculated directly from the energy of yellow light}$ is a false statement.
Hence (b) is the correct answer.
