Chemical Bonding · Class 11 · JEE Main Previous Year Question
The hybridisations of the atomic orbitals of nitrogen in , and respectively are:
- a
and sp
- b
and
- c
and
- d✓
and
and
🧠 Hybridisation = steric number (σ-bonds + lone pairs) on the central N. Count electron groups for each species.
| Species | σ-bonds | LP | Steric no. | Hybridisation | |---|---|---|---|---| | | 2 | 1 | 3 | sp² | | | 2 | 0 | 2 | sp | | | 4 | 0 | 4 | sp³ |
🗺️ is isoelectronic with : N sits between two O with double bonds and no lone pair → linear → sp. has an extra lone pair that reduces the geometry to sp² (bent shape). loses its lone pair on gaining H⁺ → fully sp³.
