According to Valence Bond Theory (VBT), what is the hybridisation and geometry of the diamagnetic co — Coordination Compounds Chemistry Question

💡 Solution & Explanation

$Ni^{2+}$ has a $3d^8$ configuration. $CN^-$ is a strong field ligand, forcing pairing of the two unpaired 3d electrons. This vacates one 3d orbital, resulting in $dsp^2$ hybridisation and a square planar geometry.
