Current Question (ID: 21571)

Question:

$\text{Match List-I (Complexes) with List-II (Colour) and choose the correct option:}$ $\begin{array}{|c|c|} \hline \text{List-I} & \text{List-II} \\ \hline (i) \; \text{Fe}_4[\text{Fe(CN)}_6]_3 & (A) \; \text{Red} \\ (ii) \; [\text{Fe(SCN)}]^{2+} & (B) \; \text{Green} \\ (iii) \; \text{FeSO}_4 \cdot 7\text{H}_2\text{O} & (C) \; \text{Prussian blue} \\ \hline \end{array}$

Options:

1. $(i)-(C), (ii)-(A), (iii)-(B)$
2. $(i)-(B), (ii)-(A), (iii)-(C)$
3. $(i)-(A), (ii)-(B), (iii)-(C)$
4. $(i)-(C), (ii)-(B), (iii)-(A)$

Solution:

$\text{Hint: Fe}_4[\text{Fe(CN)}_6]_3 \text{ exhibits a Prussian blue colour}$ $(i)-(C), (ii)-(A), (iii)-(B)$
