JEE MAIN - Chemistry Hindi (2024 - 30th January Evening Shift - No. 17)
The orange colour of $$\mathrm{K_2Cr_2O_7}$$ and purple colour of $$\mathrm{KMnO_4}$$ is due to
Charge transfer transition in both.
$$\mathrm{d} \rightarrow \mathrm{d}$$ transitions in $$\mathrm{KMnO}_4$$ and charge transfer transitions in $$\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7$$.
$$\mathrm{d} \rightarrow \mathrm{d}$$ transitions in both
$$\mathrm{d} \rightarrow \mathrm{d}$$ transitions in $$\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7$$ and charge transfer transitions in $$\mathrm{KMnO}_4$$.
