VSEPR Flashcard

What is VSEPR theory?

Back

VSEPR (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 repel bonding pairs, affecting the overall shape of the molecule.
