The hybridization states of the central atom in the complexes , , and are respectively: — Coordination Compounds Chemistry Question

💡 Solution & Explanation

$CN^-$ and $NO_2^-$ are strong field ligands. All force pairing in $Fe^{3+}$ ($d^5$), $Fe^{2+}$ ($d^6$), and $Co^{3+}$ ($d^6$). Thus, all are inner orbital $d^2sp^3$ complexes [40].
