Question

Intermolecular forces acting among the molecules are

• A. attractive in nature
• B. repulsive in nature
• C. both (a) and (b)
• D. none of these

Answer 1

The correct option is C both (a) and (b)

Intermolecular forces act between molecules of a substance and arises due to the charge distribution inside a molecule. The molecules exists in a polarized state ( due to distortion of the electron cloud by adjacent molecule).


Hence attractive forces operate between the oppositely charged poles and repulsive forces operate between similarly charged poles.
$\therefore$ Intermolecular forces includes attractive forces as well as repulsive forces between the molecules.
