What could make London Dispersion Forces stronger?

• Heating up the molecules

• Heavier molecules

• Molecules with more electrons

Which force is only found between polar covalent molecules?

• Ionic bond

• Dipole Dipole

• London Dispersion Force

• Covalent bond

In this force, electron movement cause a slight charge at a single instant. This charge is temporary.

• Hydrogen bonding

• Dipole Dipole

• London Dispersion Forces

• Ionic Bonds

Which is not a bond, but is an intermolecular force?

• Covalent Bond

• Ionic Bond

• Hydrogen Bond

• These are all bonds

When one polar molecule attracts another polar molecule it is called:

• Hydrogen Bonds

• Dipole Dipole

• London Dispersion Force

• Ionic Bond

Which of these forces is always the strongest?

• Hydrogen bonds

• Dipole Dipole force

• London Dispersion force

• Ionic bonds

Type of intermolecular force present in HF.

• dipole dipole
• dispersion
• H-bond
• ionic

Type of intermolecular force present in I₂, Br₂, and Cl₂.

• dipole dipole
• H-bond
• dispersion
• metallic

Intermolecular forces are the forces

• within molecules
• between molecules

Hydrogen bonding occurs when a hydrogen atom bonded to N, O, or F is attracted to another molecule's N, O or F atom. Which of the following can participate in hydrogen bonding?

• CBr₄

• NO₂

• H₂S

• NH₃
