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

Explanation for correct answer:-

Option (C) Oxygen, water, sugar

• Among the three states of matter, solid has the strongest force of attraction between its particles due to its closely packed nature.
• Gas has the least force of attraction between its particles, this is because of its loosely packed nature.
• Here in this option, oxygen is the gas, thus its force of attraction between its particles is the least.
• On the other hand sugar generally exist in the cube structure, thus making it a solid and, hence it's force of attraction between its particles is the most.
• Thus the increasing order of the force of attraction between the particles is: Oxygen<water<sugar.
• Hence it is the correct option

Explanation for correct answer:-

Option (A) Water, air, wind

• Here in this option, both wind and air are gas, thus the force of attraction between its particles is the least.
• On the other hand water is the liquid here which has more intermolecular force of attraction than gas.
• Hence it is the incorrect option.

Option (B) Air, sugar, oil

• Here in this option, air is the gas, thus its force of attraction between its particles is the least.
• On the other hand sugar generally exist in the cube structure, thus making it a solid and, hence it's force of attraction between its particles is the most.
• Oil here is the liquid, which means that its intermolecular force of attraction is greater than that of air but less than sugar.
• Thus the increasing order of the force of attraction between the particles is: Air<sugar<oil, which is wrong.
• Hence it is the incorrect option.

Option (D) Salt, juice, air

• Here in this option, air is the gas, thus its force of attraction between its particles is the least.
• On the other hand Salt generally exist in the cube structure, thus making it a solid and, hence its force of attraction between its particles is the most.
• juice here is the liquid, which means that its intermolecular force of attraction is greater than that of air but less than salt.
• Thus the increasing order of the force of attraction between the particles is: Salt<juice<air, which is wrong.
• Hence it is the incorrect option.

Therefore, option (C) Oxygen, water, sugar represents the correct arrangement.
