Question

(A) $1$. $KMnO_4$ is intensely colored due to $L \rightarrow M$ (Ligand to Metal) charge transfer,where electrons transfer from $O^{2-}$ to $Mn^{7+}$.

Vedclass · Accepted Answer

$KMnO_4$ is violet/purple/dark pink due to $L \rightarrow M$ charge transfer.

Vedclass · Answer

(A) $1$. $KMnO_4$ is intensely colored due to $L \rightarrow M$ (Ligand to Metal) charge transfer,where electrons transfer from $O^{2-}$ to $Mn^{7+}$. This is correct.$2$. $TiF_6^{3-}$ $(d^1)$ is colored due to $d-d$ transition,and $Cu_2Cl_2$ is colorless due to $d^{10}$ configuration. This is incorrect.$3$. $AgCl$ is white (colorless) and $CrO_2Cl_2$ is colored due to charge transfer,not just polarization. This is incorrect.$4$. The crystal field splitting energy $\Delta_o$ for $NH_3$ is greater than $H_2O$. Since $E = hc/\lambda$,a higher $\Delta_o$ corresponds to a lower $\lambda$. Thus,$[Co(H_2O)_6]^{2+}$ absorbs at a higher $\lambda$ than $[Co(NH_3)_6]^{2+}$. This is correct.Note: Both $A$ and $D$ are scientifically correct statements.
