Question

The intermolecular force is the weakest in

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

Answer 1

The correct option is C

(c) gases

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

correct option explanation:

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

Incorrect option explanation:

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

(d) 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.

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

(d) both b and c: only gases have the weakest force of attraction, while in case they have the moderate intermolecular force of attraction.

Concluding statement: The intermolecular force is the weakest in gases.Therefore,option(c) is the correct answer.
