Question

The force of attraction between unlike molecules is called

• A. cohesive force
• B. adhesive force
• C. bonding
• D. none of these

Answer 1

The correct option is B

adhesive force

Correct answer: Option (B)

Adhesive force

1. The force of attraction between unlike molecules is called the force of adhesion.
2. Some water particles remain stuck to the glass after a glass of water has been emptied.
3. This is caused by the force of adhesion, or the force of attraction, between the molecules of glass and water.

Explanation for incorrect options

(A): Cohesive force

1. Cohesive force is the term used to describe the attraction between molecules of the same type.
2. For instance, the force of cohesion between the molecules of water maintains the substance's molecular link.

(C): Bonding

1. Chemical bonding is the process through which two or more atoms, molecules, or ions form a chemical link to create a chemical compound.
2. The atoms in the resultant molecule are held together by these chemical bonds.

Thus, the force of attraction between unlike molecules is called adhesive force.

Hence, option (B) is correct.
