Select correct statement(s) regarding octahedron complex having CFSE = -1.2 \Delta_o. — Coordination Compounds Chemistry Question

💡 Solution & Explanation

CFSE = -1.2 \Delta_o corresponds to either a d^3 or d^8 octahedral complex. For these configurations, the terms "high spin" and "low spin" lose significance, the hybridization is always fixed (d^2sp^3 for d^3 and sp^3d^2 for d^8), and they have 3 or 2 unpaired electrons respectively (\mu = \sqrt{15} or \sqrt{8} B.M.).
