Question

The intermolecular forces are minimum in the case of

• A. Solids
• B. Liquids
• C. Gases
• D. Only water

Answer 1

The correct option is C

Gases

The explanation for the correct option:

(c) Gases:

• In the case of gases, the molecules are very far apart from each other.
• As intermolecular spaces are too large, therefore intermolecular forces are almost negligible.

The explanation for the incorrect option:

(a) Solids:

• In the case of solid, the molecules are very tightly packed.
• The intermolecular spaces between the molecules are very small.
• Thus, they have very strong intermolecular forces of attraction.

(b) Liquids:

• In the case of liquids, the molecules are not very tightly packed.
• The intermolecular spaces between the molecules are far more as compared to solid
• Thus, the molecules do not have a strong intermolecular force.

(d) Only water:

• As water is liquid, the molecules are not very tightly packed.
• Furthermore, they can flow and cannot be held without a container.
• They cannot be compressed.

Thus, Option (c) i.e Gases is the correct answer.
