Chemical Bonding · Class 11 · JEE Main Previous Year Question
The molecule in which hybrid MOs involve only one d-orbital of the central atom is:
- a✓
- b
- c
- d
🧠 Identify which complex/molecule uses exactly one d-orbital in its hybridization scheme.
🗺️ Count d-orbitals in each hybridization:
| Species | Hybridization | d-orbitals used | |---------|--------------|----------------| | | dsp² (square planar, Ni²⁺ is d⁸ strong field) | 1 ✓ | | | sp³d² (5 bonds + 1 LP = 6 pairs) | 2 ✗ | | | sp³d² (4 bonds + 2 LP = 6 pairs) | 2 ✗ | | | d²sp³ (octahedral, 6 bonds = 6 pairs) | 2 ✗ |
⚡ In dsp² hybridization (e.g. square planar Ni²⁺ complexes), the d-orbital involved is the — just one. This is characteristic of strong-field d⁸ complexes.
