Regarding dipole - dipole attractions the incorrect statement is

Options

A. Dipole - dipole attractions are more if the molecules have high dipole moment values.
B. In liquid HBr, dipole - dipole attractions are present.
C. Dipole - Dipole interaction energy between stationary polar molecules `prop r^(-3)`
D. Dipole - dipole interaction energy between rotating molecules `prop r^6`

Explanation

Dipole -dipole between rotating molecules `alpha = 1/(gamma^6)`.
