Question

how does the force to break surface tension polar and nonpolar substances?
a the force is lower for polar substances
b the force is higher for nonpolar substances
c the force is higher for polar substances

Explanation:

Polar substances have stronger intermolecular forces (such as hydrogen - bonding and dipole - dipole interactions) compared to non - polar substances which mainly have weak London dispersion forces. Surface tension is related to the strength of intermolecular forces at the surface. Stronger intermolecular forces require more force to break the surface tension.

Answer:

C. The force is higher for polar substances
