Intermolecular Forces and Their Types

What are intermolecular forces?

• Forces that only exist in ionic compounds

• Forces that repel molecules from each other

• Attractive forces between neighboring molecules

• Forces that hold atoms together in a molecule

Which type of intermolecular force is present in polar molecules like hydrogen chloride?

• Covalent bonds

• Metallic bonds

• Ionic bonds

• Permanent dipole-dipole forces

What makes hydrogen bonds stronger than regular dipole-dipole attractions?

• They occur between any two atoms

• They involve hydrogen and a highly electronegative atom

• They are the same as covalent bonds

• They only occur in metals

What are van der Waals' forces?

• Forces that are stronger than covalent bonds

• Induced dipole-dipole interactions

• Forces that only occur in ionic compounds

• Permanent dipole-dipole interactions

Why do van der Waals' forces increase with the number of electrons?

• Because more electrons mean more permanent dipoles

• Because more electrons lead to stronger ionic bonds

• Because more electrons increase the likelihood of induced dipoles

• Because more electrons decrease the boiling point
