Question 23

Van der Waals forces are:

Answer 23

An intermolecular force that is caused by momentary dipoles. It is stronger in molecules with greater surface area, but is the weakest intermolecular force.

Question 24

Dipole-Dipole interactions:

Answer 24

Created by polar molecules, they align dipoles and create a chain of sorts, relativly strong intermolecular force.

Question 25

Hydrogen bonding

Answer 25

A dipole-dipole interaction that involves hydrogen bonded to N, O, or F. It’s a stronger dipole-dipole interaction because of the large electronegativity difference.
