Question

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

oxygen, sugar, water

Answer 1

1. Oxygen is an example of gas, sugar is an example of a solid, and water is an example of a liquid.
2. The molecules of a solid are closely packed together. This shows that the intermolecular force is the strongest in solids.
3. The molecules of a liquid are not closely packed. This shows that the intermolecular force is slightly weaker.
4. The molecules of a gas are loosely packed. This shows that the intermolecular force is the weakest.
5. Hence, the increasing order of intermolecular force of attraction between the given particles of oxygen, sugar, and water is $Oxygen<Water<Sugar.$
