Count electron domains on nitrogen for four nitrogen oxo species, see each one drawn to scale at its experimental bond angle, and rank them: a lone pair closes the angle below 120 degrees while a single odd electron lets it open above.
Open the interactive simulationSub-topics covered
- Electron-domain (steric number) counting
- Lone-pair vs bond-pair vs single-electron repulsion
- Odd-electron (radical) species
- Resonance and fractional bond order
- Isoelectronic series
- Walsh's rules for AB2 triatomics
What it teaches
- Steric number and electron geometry
- Deviation from the ideal 120 degree angle
- Symmetry-fixed geometries (D3h, D-infinity-h)
- Electron count controls bending in AB2 species
