Intermolecular Forces and Properties Review

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?

• Dipole-Dipole Interaction

• Ion-Dipole Interaction

• Hydrogen Bonds

• Covalent Bond

• Ionic Bond

Rank these in order of strength:
