Force of attraction between molecules of the same substance is called ______.

cohesive force

The correct answer is option 2. cohesive force.

The force of attraction between molecules of the same substance is called Cohesive force.

Cohesive forces are the intermolecular forces that hold together molecules of the same substance. These forces are responsible for the tendency of liquid molecules to stick together, forming droplets, and the tendency of solid molecules to form a solid structure. Cohesive forces play a significant role in determining the properties of liquids, such as viscosity and surface tension.
