Vedclass · Accepted Answer

$ \Delta_0 $ values of $(A)$ and $(B)$ are calculated from the energies of violet and yellow light,respectively

Vedclass · Answer

(A) The colour observed is the complementary colour of the light absorbed by the complex.$ \Delta_0 $ is calculated from the energy of the absorbed light,not the emitted (observed) light.Since $(A)$ is violet,it absorbs yellow light,and since $(B)$ is yellow,it absorbs violet light.Therefore,the statement that $ \Delta_0 $ values are calculated from the energies of violet and yellow light respectively is incorrect.

Two complexes $[Cr(H_2O)_6]Cl_3 \ (A)$ and $[Cr(NH_3)_6]Cl_3 \ (B)$ are violet and yellow coloured respectively. The incorrect statement regarding them is
