Which among the following has the strongest intermolecular force between their molecules?

  1. Milk

  2. Water

  3. Sodium chloride

  4. Air

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Intermolecular forces: water has hydrogen bonding (strongest), milk contains water and other components with weaker overall forces, sodium chloride is ionic solid (not about intermolecular forces between molecules in liquid/gas state), air has very weak London dispersion forces. Water's extensive hydrogen bonding network gives it the strongest intermolecular forces among the options.
