Intermolecular Forces

List the following from strongest to weakest.

• Hydrogen bonds

• dipole-dipole interactions

• ion-dipole bonds

• London Dispersion Forces / Van Der Waals Forces

More mass : Stronger gravity :: More mass : ​ ​ (a)   Van Der Waals Forces

• Stronger
• Weaker
• Equal
• Unknown

Potassium is dissolved in an aqueous solution. Click the part of the molecule that will have an affinity to the solute.

Water is liquid at room temperature, but carbon dioxide is not. Why is that?

• CO₂ is straight, while H₂O is bent.

• H₂O has weaker intermolecular forces due to dipole-dipole interactions.

• H₂O has stronger intermolecular forces due to hydrogen bonding.

• CO₂ has less mass than H₂O.
