MOLECULAR GEOMETRY

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main principle of VSEPR theory?

Back

Molecules adjust their shapes to keep pairs of valence electrons as far apart as possible.

Front

What shape is formed by a molecule with two bonding pairs and no lone pairs?

Back

Linear.

Front

What shape is formed by a molecule with three bonding pairs and one lone pair?

Back

Trigonal pyramidal.

Front

What shape is formed by a molecule with two bonding pairs and one lone pair?

Back

Bent.

Front

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

Back

Tetrahedral.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, altering the shape.
