AP Chemistry Intermolecular Forces

Does HF have hydrogen bonding?

• yes

• no

In a nonpolar covalent bond, the electrons gather around...

• Mostly the atom with the greatest electronegativity

• The atom with the lowest electronegativity

• Each atom Equally

• Only the atom with the greatest electronegativity

If we heat water then:

• some of the bonds between the hydrogen and oxygen break

• all of the bonds between the hydrogen and oxygen break

• some of the bonds between water molecules will break

Intermolecular forces for: CO₂

• London dispersion Forces

• Dipole dipole

• Hydrogen bonding

Propane is a gas at STP, while bromine is a liquid at STP. Which statement correctly explains these observations?

• Bromine has weaker intermolecular forces than propane does

• Bromine has greater molecular polarity than propane does

• Bromine has weaker molecular polarity than propane does

• Bromine has stronger intermolecular forces than propane does

Does NH₃ or PH₃ have a higher boiling point?

• NH₃ because it has the strongest intermolecular forces

• PH₃ because it has the strongest intermolecular forces

• NH₃ because it has the weakest intermolecular forces

• PH₃ because it has the weakest intermolecular forces

Which substance would we predict to have the lowest boiling point?

• CH₄

• NaCl

• H₂O

• MgF₂
