Question
Which of the following coordination entities forms an outer orbital complex with $sp^3d^2$ hybridization?
Answer: D
💡 Solution & Explanation
$F^-$ is a weak field ligand, unable to force pairing of the $d^6$ electrons in $Co^{3+}$. Hence, it uses outer 4d orbitals, resulting in $sp^3d^2$ [38, 39].
