VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main purpose of VSEPR theory?

Back

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

Front

What shape does a molecule with 4 bonding pairs and no lone pairs have?

Back

Tetrahedral.

Front

What is the molecular shape of water (H2O)?

Back

Bent or V-shaped.

Front

How many lone pairs are present in ammonia (NH3)?

Back

One lone pair.

Front

What is the bond angle in a tetrahedral molecule?

Back

Approximately 109.5 degrees.

Front

Which molecule has a trigonal planar shape?

Back

BF3 (Boron Trifluoride).

Front

What is the effect of lone pairs on bond angles?

Back

Lone pairs repel more strongly than bonding pairs, reducing bond angles.

Front

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

Back

Linear.

Front

How does electronegativity affect molecular shape?

Back

Electronegativity differences can lead to polar bonds, affecting the overall shape.
