Give magnitude of energy of force and value of interaction process with example.

Explanation

Dipole - Dipole force : 1 to 3 K cal `mol^(-1)`
e.g., : `SO_(2), NO, HCl`
Interaction energy in rotational molecule `prop (1)/(r^(6))`
Interaction energy energy in stable molecule `prop (1)/(r^(3))`
(We go to closer energy release).
If distance between molecules `lt` 500 pm. Then this forces present.
