AP Bonding and VSEPR

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between the electron pairs in the valence shell of the central atom.

Front

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

Back

Tetrahedral.

Front

What is the bond angle in a linear molecule?

Back

180 degrees.

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 two lone pairs?

Back

Bent.

Front

How do lone pairs affect molecular shape?

Back

Lone pairs take up more space than bonding pairs, causing the bond angles to be smaller than expected.

Front

What is the shape of a molecule with five bonding pairs?

Back

Trigonal bipyramidal.

Front

What is the bond angle in a trigonal planar molecule?

Back

120 degrees.

Seesaw.

Front

What is the shape of a molecule with six bonding pairs?

Back

Octahedral.
