The correct statements (s) about intermolecular forces is(are)
Options
- AThe potential energy between two point charges approaches zero more rapidly than the potential energy between
- BThe average potential energy of two rotating polar molecules that are separated by a distance r has 1 / r^3 de
- CThe dipole-induced dipole average interaction energy is independent of temperature.
- DNonpolar molecules attract one another even though neither has a permanent dipole moment.
Correct answer
C. The dipole-induced dipole average interaction energy is independent of temperature.
Step-by-step solution
(i) Ion - Ion Interaction energy 1 r Ion - dipole Interaction energy 1 r^2 Ion - dipole Interaction energy approaches zero more rapidly as ' r ' increases (ii) Rotating Polar molecules Interaction energy 1 r ^6 . (iii) Dipole - induced dipole forces are independent of temperature. (iv) Non-polar species show London dispersion forces.
