Which among the following has lowest surface tension?

Question

Which among the following has lowest surface tension? (A) Hexane (B) Water (C) CH 3 OH (D) CH 3 CH 2 OH

Tardigrade Admin · Accepted Answer

Since, surface tension depends on the attractive forces between the molecules, and hydrogen bonding a special type of dipole-dipole interactions in (b), (c) and (d) which is stronger than London forces of attraction in hexane
