VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main principle of VSEPR theory?

Back

The shape of a molecule is determined by the repulsion between electron pairs in the valence shell of the central atom.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, which can alter the expected geometry.

Front

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

Back

Trigonal pyramidal.

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees.

Front

What is the bond angle for a bent molecular geometry?

Back

Approximately 104.5 degrees.

Front

How many bonding pairs of electrons are in a water molecule (H2O)?

Back

2 bonding pairs.

Front

What is the difference between electron geometry and molecular geometry?

Back

Electron geometry considers all electron pairs (bonding and lone), while molecular geometry considers only the arrangement of bonding pairs.

Front

Can a molecule with a lone pair on the central atom have the same electron and molecular geometry?

Back

No, they will differ.

Front

What is the molecular geometry of carbon dioxide (CO2)?

Back

Linear.
