Questions and Answers

Which liquid has the highest surface tension among the ones listed?

Carbon disulfide

Pyridine

Water (correct)

The surface tension is the same for all liquids listed

What type of intermolecular forces exist in Carbon disulfide?

Dipole-dipole forces (DDF)

London dispersion forces (LDF) (correct)

Hydrogen bonding

Ionic bonding

Why does a liquid with strong intermolecular forces have higher surface tension?

Due to lower energy required to increase surface area

As weaker intermolecular forces reduce the energy needed to increase surface area

Because the surface molecules experience a weaker net pull

Strong intermolecular forces result in a greater net pull of surface molecules (correct)

What makes Pyridine different from Carbon disulfide in terms of intermolecular forces?

<p>Pyridine has hydrogen bonding, while Carbon disulfide has London dispersion forces</p> Signup and view all the answers

How do London dispersion forces contribute to surface tension?

<p>By reducing the required energy to increase surface area</p> Signup and view all the answers
