Arrange the following substances in increasing order of forces of attraction between the particles water, sugar, oxygen.

The increasing order of forces of attraction between the given particles of water, sugar and oxygen is

Oxygen <Water < Sugar.

Justification:

We know that the particles in solids are tightly packed. So the intermolecular forces between the particles are more and hence the force of attraction between the particles is also high.

In case of liquids the particles in a liquid are closely packed as compared to solids. The intermolecular forces between the particles are less as compared to solids. Hence the force of attraction is comparatively less than solids.

Now will consider gases. The particles in gases are very closely packed and are continually in random motion. The intermolecular forces are slightly less compared to liquids and very less as compared to solids. So the intermolecular forces in gases are also less compared to the other two states of matter that are solids and liquids.

Gases have the least forces of attraction, liquids have the intermediate force of attraction, and solids have the highest forces of attraction.

Here oxygen being a gas it has the least forces of attraction. Then comes water which exists in liquid state of matter and then sugar, the solid.
