Questions and Answers
Which liquid has the highest surface tension among the ones listed?
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?
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?
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)
