VSEPR Theory

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

What is the bond angle for a tetrahedral molecule?

Back

109.5 Degrees.

Front

What is the shape of a molecule with 4 bonded pairs and 0 lone pairs?

Back

Tetrahedral.

Front

How do lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonded pairs, which can alter the bond angles and overall shape of the molecule.

What is the molecular shape of a molecule with 3 bonded pairs and 1 lone pair?

Back

Trigonal Pyramidal.
