Question

Which among the following has the lowest surface tension?

Options

• Hexane

• Water

• CH₃OH

• CH₃CH₂OH

Answer 1

Hexane

Explanation:

In options (b), (c), and (d), hydrogen bonding is a unique sort of dipole-dipole interaction that is greater than the London forces of attraction in hexane because surface tension depends on the attractive forces between the molecules.
