Question

Tick the most appropriate answer:

The force of attraction between the molecules is called

• A. intermolecular attraction
• B. molecular attraction
• C. any of these
• D. molecular force

Answer 1

The correct option is A

intermolecular attraction

• A molecule is defined as the smallest unit of matter, which has an independent existence and can retain the complete physical and chemical properties of matter.
• According to the kinetic theory of gases, the molecules always attract each other.
• The force of attraction between similar kinds of molecules is called the force of cohesion.
• The force of attraction between different kinds of molecules is called the force of adhesion.
• The forces of attraction between the molecules (cohesive force or adhesive force) are called intermolecular forces of attraction.

Explanation for incorrect option:

Option B:

Molecular attraction is physical affinity. It is the tendency of molecules with unlike electrical charges to attract each other.

Option D:
Molecular force is the attraction force between two atoms or molecules. It is how strong the bonds of molecules are and also how molecules bond to each other.

Hence, the correct answer is an option (A).
