In Na2[Fe(CN)5NO], sodium nitroprusside : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Sodium nitroprusside consists of Na^+ cations and the complex [Fe(CN)5NO]^2- anion. Step 2: In this complex, the nitric oxide ligand is coordinated as a nitrosonium cation (NO^+). Step 3: Calculating the oxidation state of Fe: x + 5*(-1) + 1*(+1) = -2 => x - 4 = -2 => x = +2. Since both statements (a) and (b) are correct, option (c) is the correct choice.
