The magnitude of the surface tension of liquid depends on the attractive forces between the molecules. Arrange the following in increasing order of surface tension: Water, alcohol (C2H5OH) and hexane [CH3(CH2)4CH3)].

Hydrogen bonding is stronger in water than in alcohol. So, water has a strong intermolecular attraction than alcohol. The increasing order of surface tension is – Hexane< alcohol< water.
