Calculate the Effective Atomic Number (EAN) of iron in . (Atomic number of Fe = 26) — Coordination Compounds Chemistry Question
Question
Calculate the Effective Atomic Number (EAN) of iron in $K_4[Fe(CN)_6]$. (Atomic number of Fe = 26)
Answer: C
💡 Solution & Explanation
Fe is in $+2$ oxidation state. $EAN = Z - \text{O.S.} + 2(\text{C.N.}) = 26 - 2 + 2(6) = 24 + 12 = 36$, matching the noble gas Krypton.
