Questions using intermolecular force
Problem 1
Which type of intermolecular force is the strongest?
- dipole–dipole forces
- hydrogen bonds
- there are no forces between molecules
- London dispersion forces
Answer and explanation
hydrogen bonds
Hydrogen bonds are the strongest intermolecular force, followed by dipole–dipole, then London dispersion.
