VSEPR and Molecular Shape

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.

What does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion.

What is the molecular shape of a molecule with two bonding pairs and one lone pair?

Back

The molecular shape is Bent/Angular.

Front

What is the molecular shape of a molecule with four bonding pairs and no lone pairs?

Back

The molecular shape is Tetrahedral.

Front

What is the molecular shape of a molecule with three bonding pairs and one lone pair?

Back

The molecular shape is Trigonal Pyramidal.

Front

What is the molecular shape of a molecule with five bonding pairs?

Back

The molecular shape is Trigonal Bipyramidal.

Front

What is a lone pair?

Back

A lone pair is a pair of non-bonding electrons located on the central atom of a molecule.

Front

How does a lone pair affect molecular shape?

Back

A lone pair occupies space and repels bonding pairs, which can alter the molecular geometry.

Front

What is the molecular shape of a molecule with two bonding pairs and no lone pairs?

Back

The molecular shape is Linear.

Front

What is the effect of electronegativity on molecular shape?

Back

Electronegativity can influence the distribution of electron density, affecting the polarity and shape of the molecule.
