Question

A few substances are arranged in the increasing order of forces of attraction between their particles. Which one of the following represents a correct arrangement?

• A. Water, air, wind
• B. Air, sugar, oil
• C. Oxygen, water, sugar
• D. Salt, juice, air

Answer 1

The correct option is C Oxygen, water, sugar

Intermolecular forces are forces of attraction or repulsion which act between neighbouring particles ($atoms,moleculesorions$). These force keep a molecule together.
In solid, a particle can vibrate but they can not move. Sugar is solid.
In liquid, the force of attraction is weaker than solid. Water is a liquid.
In gas, the particle moves fast in a random direction so there is no force of attraction. Oxygen is a gas.
$Oxygen,water,sugar$ is the increasing order of forces of attraction.
Option $C$ is correct.
