VSEPR

Front

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 the electron pairs in the valence shell of the central atom.

Front

What is the effect of lone pairs on molecular geometry?

Back

Lone pairs repel more strongly than bonded pairs, affecting the overall shape of the molecule.
