which liquid has highest surface tension?

CH3 - CO - OH

CH3 -CH2 -O - CH3

CH3 - CH2 - S - CH3

CH3 - CH2 - CH2 - Cl

Solution

Surface tension depends by molecular interactions in the substance.

Surface tension is the tendency of a liquid to be attracted to itself. The result is that liquids tend to clump into droplets because a sphere/ball is the configuration where all the molecules are closest together. Liquids have varying surface tension, some have a stronger tendency to clump together than others. For example water has more surface tension than ethanol.
