Questions 1 - 1

Which of the following organizes the forces from strongest to weakest?

Covalent bonding, hydrogen bonding, dipole-dipole interactions, van der Waals forces

Hydrogen bonding, covalent bonding, dipole-dipole interactions, van der Waals forces

Van der Waals forces, dipole-dipole interactions, hydrogen bonding, covalent bonding

Van der Waals forces, hydrogen bonding, covalent bonding, dipole-dipole interactions

Dipole-dipole interactions, hydrogen bonding, covalent bonding, van der Waals forces

Covalent bonds are by far the strongest, requiring $200-1000\frac{kJ}{mol}$ to be broken.

Next are hydrogen bonds, which require between $12-30 \frac{kJ}{mol}$ to be broken.

Next are dipole-dipole interactions, which require $5-20 \frac{kJ}{mol}$ to be broken.

Finally, van der Waals forces are the weakest of those listed, requiring $0.4-4 \frac{kJ}{mol}$ to be broken.
