Finely divided iron combines with $\mathrm{CO}$ to give:
1 $\mathrm{Fe}(\mathrm{CO})_{5}$
2 $\mathrm{Fe}_{2}(\mathrm{CO})_{9}$
3 $\mathrm{Fe}_{3}(\mathrm{CO})_{12}$
4 $\mathrm{Fe}(\mathrm{CO})_{6}$
Explanation:
(A) : Finely divided iron combines with CO ligand and forms $\mathrm{Fe}(\mathrm{CO})_{5}$. $\mathrm{Fe}+5 \mathrm{CO} \longrightarrow \mathrm{Fe}(\mathrm{CO})_{5}$

Colour of $\mathrm{V}^{4+}$ ion is
1 green
2 violet
3 pink
4 blue
Explanation:
(D) : Colour of $\mathrm{V}^{4+}$ ion is blue. The colour observed corresponds to the complementary colour of the light absorbed. The frequency of light absorbed is determined by the nature of the ligand. Thus, most of the compounds of transition metals are coloured due to d-d transition.
