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 shape of molecules based on the repulsion between electron pairs.

Front

How do lone pairs affect molecular shape according to VSEPR?

Back

Lone pairs take up more space than bonding pairs, affecting the overall shape.

Front

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

Back

Tetrahedral.

Front

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

Back

Bent.

Front

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

Back

Trigonal pyramidal.

Front

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

Back

Linear.

Front

How many degrees are the bond angles in a tetrahedral molecule?

Back

Front

What is the bond angle in a trigonal planar molecule?

Back

120 degrees.

Front

What is the bond angle in a bent molecule with two lone pairs?

Back
