What are intramolecular forces?

• Forces between molecules

• Forces within a single molecule

• Forces between atoms in different molecules

• Forces that only occur in ionic compounds

Which of the following are types of intramolecular forces?

• Hydrogen bonds, metallic bonds, and dipole-dipole interactions

• Ionic bonds, covalent bonds, and metallic bonds

• Ionic bonds, covalent bonds, and hydrogen bonds

• Van der Waals forces, ionic bonds, and covalent bonds

What are intermolecular forces?

• Forces within a single molecule

• The repulsive forces between covalently bonded molecules

• The attractive forces between covalently bonded molecules

• Forces between atoms within a nucleus

Are intermolecular forces generally stronger or weaker than intramolecular forces?

• Stronger

• Weaker

• The same strength

• There is no general comparison

What type of force is represented by the dotted line between the two molecules on the left side of the image?

What are London dispersion forces?

• The strongest intermolecular forces

• Temporary attractive forces that result from temporary shifts in electron density between adjacent atoms

• Permanent attractive forces between molecules

• Forces that only occur in solid materials

What can a temporary dipole in one atom or molecule induce in a neighboring atom or molecule?

• A permanent dipole

• A covalent bond

• An induced dipole

• A hydrogen bond

How are atoms or molecules held together by London dispersion forces?

• By a strong ionic bond

• By a permanent dipole-dipole interaction

• By a weak attraction for an instant

• By a metallic bond

Among the intermolecular forces, where do London dispersion forces rank in terms of strength?

• They are the strongest

• They are of moderate strength

• They are the weakest

• They are the only type of intermolecular force
