TS EAMCET 5-Aug-2021 Shift 1 Question Paper

(b) Dipole-dipole interaction energy between polar molecules in solids depends on the distance between them as per the following relation. Dipole-dipole interaction energy ∝1∕r3 and that between rotating polar molecules is proportional to l∕r6, where r is the distance between polar molecules.
So option (b) i.e. ‌

1

r3

and ‌

1

r6

is correct.
