Which has a greater surface tension: H20 or CH3CH2CH2CL? Explain

Water will have higher surface tension.

Explanation:

There are strong hydrogen bonds and strong intermolecular forces present in water. Water is polar in nature that is why surface tension is present in it. The force of attraction between the particles is the main factor for surface tension.

The cohesion force in the liquid causes surface tension.

Since the other substance is acetone which does not form strong intermolecular forces hence it has low value of surface tension. They have low cohesive forces and get stick to the surface and are spilled instead of attaining minimal volume.
