VSEPR REVIEW

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the primary purpose of VSEPR theory?

Back

To predict the molecular shape based on the repulsion between electron pairs.

Front

What molecular shapes are typically associated with unshared pairs of electrons?

Back

Bent and Pyramidal.

Front

How do lone pairs affect molecular geometry?

Back

Lone pairs occupy space and repel bonding pairs, altering the shape of the molecule.

Front

What is a lone pair?

Back

A pair of non-bonding electrons on the central atom.

Front

According to VSEPR theory, what do molecules do to minimize repulsion?

Back

They adjust their shapes to keep electron pairs as far apart as possible.

Front

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

Back

Tetrahedral.

Front

How many bonds are formed in a carbon dioxide (CO2) molecule?

Back

2 double bonds.

Front

What is the effect of double bonds on molecular shape according to VSEPR?

Back

Double bonds are treated as a single electron pair, affecting the overall geometry.

Front

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

Back

Bent.
