The substance with the highest surface tension - e. HOCH2CH2OH.
Surface tension is the elastic tendency of a fluid, caused by the attraction of particles in the surface which makes it acquire the least surface area.
- it depends on intermolecular forces like hydrogen bonding, Vanderwall forces, ion-dipole, and ion-induced dipole interactions.
- The higher the intermolecular forces higher will be the surface tension.
- Among all these intermolecular forces, hydrogen bonding is the strongest.
- So from given options (a) and (e) have -OH functional group and forms H-bonding.
- Among these two options, option (e) has 2-OH groups so (e) will have more extensive H-bonding.
Thus, The substance with the highest surface tension - e. HOCH2CH2OH.
