Vedclass · Answer

(C) Step $1$: Identify the atomic number $(Z)$ of the central metal ion $Fe$. $Z = 26$.Step $2$: Determine the oxidation state of $Fe$ in $[Fe(CN)_6]^{3-}$. Let it be $x$. $x + 6(-1) = -3$, so $x = +3$.Step $3$: Calculate the number of electrons in the $Fe^{3+}$ ion. $26 - 3 = 23$.Step $4$: Calculate the number of electrons donated by $6$ ligands $(CN^-)$. Each $CN^-$ donates $2$ electrons. $6 	imes 2 = 12$.Step $5$: Calculate $EAN = (Z - 	ext{oxidation state}) + (2 	imes 	ext{coordination number}) = 23 + 12 = 35$.
