Question

Identify the wrong statement among the following.

• A. In solids, molecules are closely packed.
• B. In solids, molecules have very strong intermolecular forces of attraction.
• C. In solids, molecules have only vibratory motion about their mean positions.
• D. In solids, molecules possess very high kinetic energy

Answer 1

The correct option is D

In solids, molecules possess very high kinetic energy

Explanation for the correct option: d) Solids are dense materials with tightly packed molecules, and their molecules exert larger intermolecular forces, resulting in lower velocity and less kinetic energy for molecules in solids.

Explanation for incorrect options: a) Because of the high intermolecular forces of attraction, the molecules are most closely packed in the solid-state.

b) Particles have no "time" to move about due to the solid's low kinetic energy, so they have more "time" to be attracted. As a result, solids have the most powerful intramolecular forces.

c) Solids have an extremely strong intermolecular bonding type. This results in the creation of an extremely dense structure in which the particles within the solid are unable to move around freely. As a result of the kinetic energy, the particles can only oscillate in their fixed positions.

Conclusion: Hence, option (d) is correct.
