Vedclass · Answer

(D) The energy of absorbed light $(\Delta_o)$ is inversely proportional to the wavelength of absorption $(\lambda)$: $\Delta_o \propto \frac{1}{\lambda}$.Stronger ligands cause greater crystal field splitting $(\Delta_o)$, which corresponds to higher energy and shorter wavelength of absorption.The spectrochemical series for the given ligands is: $H_2O As the ligand strength increases, the splitting energy $(\Delta_o)$ increases, and therefore the absorbed wavelength $(\lambda)$ decreases.Thus, the increasing order of wavelength is: $[Co(en)_3]^{3+} < [Co(NH_3)_6]^{3+} < [Co(H_2O)_6]^{3+}$.

The correct increasing order for the wavelengths of absorption in the visible region for the complexes of $Co^{3+}$ is:
