Intermolecular Forces Quiz

What is an intermolecular force?

• A force within a molecule

• A force that holds atoms together in a molecule

• A force that holds groups of molecules together

• A force that breaks molecules apart

Where do intramolecular forces occur?

• Between molecules

• Within a molecule and found between the atoms that create the ionic or covalent bonds.

• Outside the molecule

• In the space between atoms

What is the role of intermolecular forces in matter?

• They allow molecules to exist as independent units

• They prevent molecules from forming liquids and solids

• They hold groups of molecules together to form liquids and solids; gases are formed by very weak intermolecular forces.

• They break down molecules into atoms

Diagram showing intramolecular and intermolecular forces in molecules; select the correct statement about these forces.

• Intramolecular forces are stronger than intermolecular forces

• Intermolecular forces are stronger than intramolecular forces

• Intramolecular forces and intermolecular forces are equally strong

• There are no forces between molecules

What are the three types of intermolecular forces discussed in this activity?

• Ionic bonds, covalent bonds, metallic bonds

• Dipole-dipole interactions, hydrogen bonding, dispersion forces

• Van der Waals forces, ionic interactions, hydrogen bonds

• Covalent bonds, metallic bonds, dispersion forces

What symbols are used to represent the partial charges at the ends of polar molecules?

• α+ and α-

• δ+ and δ-

• β+ and β-

• γ+ and γ-

Would you expect nonpolar molecules to "stick together" more or less effectively than polar molecules?

• More effectively, due to stronger dipole-dipole interactions

• Less effectively, due to weaker dipole-dipole interactions

• More effectively, due to stronger hydrogen bonding

• Less effectively, due to stronger ionic bonding

What type of interaction is formed when a hydrogen atom is covalently bonded to nitrogen, oxygen, or fluorine?

• Ionic bonding

• Metallic bonding

• Hydrogen bonding

• Van der Waals forces

Is a hydrogen bond the same as a covalent bond?

• Yes, they are identical

• No, they are different types of bonds

• Yes, but only in certain conditions

• No, hydrogen bonds are weaker than covalent bonds
