Vedclass · Answer

(C) To determine the oxidation state of iron $(Fe)$ in each compound:$1$. In $FeSO_4 \cdot (NH_4)_2SO_4 \cdot 6H_2O$ (Mohr's salt),the oxidation state of $Fe$ is $+2$.$2$. In $K_4[Fe(CN)_6]$,the oxidation state of $Fe$ is $+2$ (since $4(+1) + x + 6(-1) = 0 \implies x = +2$).$3$. In $Fe(CO)_5$,$CO$ is a neutral ligand,so the oxidation state of $Fe$ is $0$.$4$. In $Fe_2O$,the oxidation state of $Fe$ is $+0.5$ (since $2x - 2 = 0 \implies x = +1$).Comparing these values,$Fe$ has the lowest oxidation state $(0)$ in $Fe(CO)_5$.

In which of the following compounds does iron have the lowest oxidation state?
