Question

The intermolecular force is the strongest in

• A. (a) solids
• B. (b) gases
• C. (c) liquids
• D. (d) both b and c

Answer 1

The correct option is A

(a) solids

intermolecular force of attraction: it is the force of attraction present between the molecules.

correct option explanation:

(a) Solids: The intermolecular force is the strongest in solids and molecules are closely packed.

Incorrect option explanation:

(b) gases: The intermolecular force of attraction is the weakest in gases.

(c) liquids: The intermolecular force of attraction present between the molecules in liquids is less than that in solids but greater than in gases and the molecules are less closely packed.

(d) both b and c: The intermolecular force of attraction present between the molecules in liquids is less than that in solids but greater than in gases and the molecules are less closely packed. But in the case of gases, it is the weakest.

Concluding statement: The intermolecular force is the strongest in solids.Therefore,option(a) is the correct answer.
