What is VSEPR Theory?

Back

VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

What is the significance of lone pairs in VSEPR Theory?

Back

Lone pairs occupy space and can affect the bond angles and overall geometry of the molecule.
