VSEPR and Molecular Geometry

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the basic premise of VSEPR theory?

Back

Electrons will try to move as far apart as possible to minimize repulsion.

Front

What molecular geometry is associated with a molecule that has four bonding pairs and no lone pairs?

Back

Tetrahedral

Front

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

Back

Linear

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees

Front

Which molecule has a bent shape due to lone pairs?

Back

H2O (water)

Front

What is the molecular geometry of methane (CH4)?

Back

Tetrahedral

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs occupy more space and can alter bond angles, leading to different shapes.

Front

What is the molecular geometry of sulfur dioxide (SO2)?

Back

Bent or angular

Front

What is the bond angle in a linear molecular geometry?

Back

180 degrees
