Front

Define molecular geometry.

Back

The three-dimensional arrangement of atoms in a molecule.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion theory; it predicts the shape of molecules based on electron pair repulsion.

Front

What is a polar molecule?

Back

A molecule with a net dipole moment due to the presence of polar bonds.

Front

What is a nonpolar molecule?

Back

A molecule that does not have a net dipole moment; the charge distribution is even.

Front

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

Back

Tetrahedral.
