Intermolecular Forces and Properties

Why are ion-dipole interactions stronger than dipole-dipole interactions?

• Because ions have a complete charge while dipoles only have partial charges

• Because ion-dipole interactions only occur in aqueous solutions

• Because dipole-dipole interactions are temporary

• Because ions are smaller than molecules

Which of the following molecules would exhibit dipole-dipole interactions?

In which of the following scenarios would ion-dipole interactions be most relevant?

• In the melting of ionic solids

• In the evaporation of water

• When an ionic compound is dissolved in water

• In the formation of a covalent bond

Which of the following molecules would have the strongest hydrogen bonding?

Dipole-induced dipole forces occur when:

• A polar molecule induces a dipole in a nonpolar molecule

• Two polar molecules interact

• A nonpolar molecule induces a dipole in another nonpolar molecule

• Two nonpolar molecules interact

The strength of Van der Waals forces depends on:

• The distance between the molecules

• The size of the molecules

• The presence of hydrogen atoms

• The polarity of the molecules
