Intermolecular Force

London forces are stronger in heavier atoms or molecules, and weaker in lighter atoms or molecules.  Which of these has the strongest London forces?

• F₂

• Br₂

• I₂

• Cl₂

Which of the following statements correctly explains why hydrogen bonding is such a strong intermolecular force?

• There is an attraction between a small, weakly electronegative hydrogen atom and a large, strongly electronegative atom of fluorine, nitrogen, or oxygen

• There is an attraction between a small, highly electronegative hydrogen atom and a large, highly electronegative fluorine atom

• There is an attraction between the hydrogen and oxygen atoms, only

• There is an attraction between the hydrogen and nitrogen atoms, only

Water has an unusually high boiling point for a molecular compound because it has

• hydrogen bonding

• ion-ion attractions

• a high density

• a large gram formula mass

Which type of IMF is responsible for the attraction pictured above?
