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 based on the repulsion between electron pairs.

Front

What shape is formed when there are two bonding pairs and one lone pair of electrons?

Back

Bent.

Front

What is the bond angle in a tetrahedral molecular shape?

Back

109.5 degrees.

Front

Which molecular shape has a bond angle of approximately 120 degrees?

Back

Trigonal Planar.

Front

What is the molecular shape of CH4?

Back

Tetrahedral.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, altering the bond angles.

Front

What is the bond angle in a bent molecular shape with two bonding pairs and one lone pair?

Back

Approximately 120 degrees.

Front

Is CO2 a polar molecule?

Back

No, it is nonpolar due to its linear shape.

Front

What is the molecular shape of BF3?

Back

Trigonal Planar.
