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 determines the shape of a molecule according to VSEPR Theory?

Back

The shape of a molecule is determined by the number of bonding pairs and lone pairs of electrons around the central atom, as they repel each other and arrange themselves to minimize repulsion.

What is the molecular geometry of a molecule with 4 bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the molecular geometry of a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal.

What is the molecular geometry of a molecule with 2 bonding pairs and 2 lone pairs?

Back

Bent.

Front

What is the molecular geometry of a molecule with 2 bonding pairs and no lone pairs?

Back

Linear.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs occupy more space than bonding pairs, which can distort the angles between bonding pairs, leading to different molecular geometries.
