Dipole -dipole interaction energy betwee...

Dipole -dipole interaction energy between polar molecule in solids depends on the radius of the molecule (r) and it is directly proportional to

A

`(1//r^(2))`

B

`(1//r^(6))`

C

(1/r)

D

`(1//r^(3))`

Text Solution

Verified by Experts

The correct Answer is:
D
Dipole-dipole interaction energy between polar molecules in solids depends on the distance between them as per following relation :
Dipole-dipole interaction energy `prop (1)/(r^(3))`
(r = radius of the moleculeunder consideration)
