Vedclass · Answer

(D) The ionic or atomic radius of $Fe$ depends on its oxidation state and the nature of the ligands attached. $1$. In $K_4[Fe(CN)_6]$,$Fe$ is in the $+2$ oxidation state. $2$. In $FeSO_4 \cdot 7H_2O$,$Fe$ is in the $+2$ oxidation state. $3$. In $FeSO_4(NH_4)_2SO_4 \cdot 6H_2O$ (Mohr's salt),$Fe$ is in the $+2$ oxidation state. $4$. In $Fe(CO)_5$,$Fe$ is in the $0$ oxidation state. Since the radius of an atom increases as the oxidation state decreases (due to lower effective nuclear charge),the $Fe$ atom in the $0$ oxidation state $(Fe(CO)_5)$ will have the largest radius compared to $Fe^{2+}$ ions.

In which of the following complexes is the radius of $Fe$ the largest?
