VSEPR Geometry Calculator
Predict molecular geometry, bond angles, and hybridization using VSEPR (Valence Shell Electron Pair Repulsion) theory.
VSEPR Input
Electron pairs involved in bonding
Non-bonding electron pairs on central atom
Common Molecules:
VSEPR Principle:
Electron pairs around a central atom arrange themselves to minimize repulsion. Lone pairs repel more strongly than bonding pairs.
Molecular Geometry
Tetrahedral
Electron Geometry: Tetrahedral
/Bond Angle
109.5°
hHybridization
sp3
SNSteric Number
4
NAXnEm
AX4E0
Examples:
CH4CCl4NH4+
Polarity Prediction:
Likely nonpolar (if all atoms are identical)
