Solution
Correct Answer:
dsp²
- Ni²⁺ configuration: Nickel (Z=28) is [Ar]3d84s2. Ni²⁺ is [Ar]3d8.
- Ligand Influence: CN− is a strong field ligand. According to Valence Bond Theory, it causes the pairing of the two unpaired electrons in the 3d shell.
- Hybridization: Pairing clears one 3d orbital. The metal uses 1 inner 3d orbital, 1 4s orbital, and 2 4p orbitals for bonding.
- Hybridization: dsp2.
- Geometry: Square Planar.
- The complex is diamagnetic (no unpaired electrons).
This hard difficulty chemistry question is from the chapter coordination compounds, covering the topic of vbt. It appeared in the 2025 exam.
