Example Questions

Example Question #1 : Nuclear Forces

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

Possible Answers:

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

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

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

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

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

Correct answer:

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

Explanation:

Covalent bonds are by far the strongest, requiring  to be broken. 

Next are hydrogen bonds, which require between  to be broken.

Next are dipole-dipole interactions, which require  to be broken.

Finally, van der Waals forces are the weakest of those listed, requiring  to be broken.
