AP bonding

The force of attraction between nonpolar molecules is:

• hydrogen bonding

• LDF

• dipole-dipole forces

• ionic forces

Which of these is not an intermolecular force?

• covalent bonding

• London dispersion forces

• hydrogen bonding

• dipole-dipole forces

Which IMF contains a temporary dipole?

• Both London dispersion and Dipole-dipole

• London dispersion forces

• hydrogen bonding

• dipole-dipole forces

What is the predominant IMF for NH₃?

• London dispersion forces

• hydrogen bonding

• dipole-dipole

• ion-dipole

In general, substances with stronger intermolecular forces have ____ boiling points than those with weaker forces

• higher

• lower

• forces and boiling point are not related

If a liquid has a high viscosity, it probably has:

• strong IMF

• weak IMF

Which is the strongest intermolecular force below?

• ionic

• hydrogen bonding

• London dispersion

• dipole-dipole

Which of these has the strongest London forces?

• F₂

• Cl₂

• Br₂

• I₂

• C₄H₁₀ because it has more H atoms, resulting in more H-bonding

• C₂H₆ because it's molecules are smaller and they can get closer to each other, resulting in stronger LDFs

• C₄H₁₀ because it has more electrons resulting in greater polarizability and stronger LDFs

• C₂H₆ because it's molecules are more polar resulting in stronger dipole-dipole attractions

What is the predominant IMF in the molecule NOF?

• LDFs

• Hydrogen bonding

• Dipole-dipole

• Polar
