Molecular Geometry #3

Which of the following statements is FALSE?

• Ionic bonding results from the transfer of electrons from one atom to another.

• Dipole moments result from the unequal distribution of electrons in a molecule.

• The electrons in a polar bond are found nearer to the more electronegative element.

• A molecule with very polar bonds can be nonpolar.

• Linear molecules cannot have a net dipole moment.
