Question

Arrange the following substances in increasing order of intermolecular forces of attraction

Salt, juice, air

Answer 1

1. Salt is an example of a solid, juice is an example of a liquid, and the air is an example of a gas.
2. The molecules of a solid are closely packed together. Thus, the intermolecular force is the strongest in solids.
3. The molecules of a liquid are not closely packed. Thus, the intermolecular force is slightly weaker.
4. The molecules of a gas are loosely packed. Thus, the intermolecular force is the weakest.

Hence, The increasing order of intermolecular force of attraction between the given particles of salt, juice, and the air is $Air<Juice<Salt.$
