Intermolecular Forces

Question 11 • *26-27 CFISD TX-Chemistry A CR

Which of the intermolecular forces below has the strongest attraction between molecules?

Answer
A
dipole-dipole interactions
B
London dispersion forces
C
hydrogen bonding
D
Van der Waals forces

Explanation

Hydrogen bonding is generally the strongest of these intermolecular attractions. It occurs when hydrogen bonded to nitrogen, oxygen, or fluorine is attracted to one of those atoms on another molecule. Dipole-dipole and London dispersion forces are usually weaker; “van der Waals forces” is a broad term that includes weaker intermolecular attractions.
