No, it depends on the type of intermolecular bonding
Surface tension is caused by attraction between liquid molecules. Different compounds have different levels of attraction.
Water and Ethanol are held together by hydrogen bonds, the strongest of all intermolecular forces. Thus water and ethanol have strong surface tension. All alcohols (-OH) and amines (-NH2) have hydrogen bonds
Propanone has permanent dipole-permanent dipole bonds. It is weaker than H-bonds but enough to provide some form of surface tension. All aldehydes (-HO) and keytones (-HO) have PD-PD attraction.
Bromine and octane have van der Waal’s forces (also known as London forces). This is the weakest type of intermolecular bond. Thus bromine and octane show much less surface tension than water. Alkanes and most nonmetallic elements have van der Waal’s forces.
