Which of the following are electrostatic interactions of permanent dipoles in polar molecules?

A. Ion-dipole forces

B. Hydrogen bonding

C. Dipole-dipole forces

D. London dispersion forces

Answer;

C. Dipole-dipole forces

Explanation; Dipole-dipole forces are electrostatic interactions of permanent dipoles in molecules; includes hydrogen bonding. These interactions align the molecules to increase the attraction. Molecules that contain dipoles are called polar molecules and are very abundant in nature. For example, a water molecule (H2O) has a large permanent electric dipole moment.
