Answer: The answer is Dipole-dipole attractions
Step-by-step explanation:
Polar molecules attract each other mainly due to the attraction between the opposite charges (positive and negative) known as DIPOLE, carried by their constituent molecules.
For example: Water (H2O) is Polar due to its dipole-dipole interaction, as the positively charged hydrogen ion (H+) is attracted to the negatively charged hydroxyl ion (OH-)
