The strongest attractive forces between molecules of Cl 2 are dispersion forces

The right solution to the given question seems to be "True".

Explanation:

Dispersion forces were already available whether the compounds or molecules are stable dipoles or not. The inter-molecular force among persistent molecular wave-guides seems to be the product of polarization as well as dispersion.Cl₂ seems to be a non-polarized molecule constructed by comparable atoms. So, the dipoles are going to be null (zero).

So that the above seems to be the right answer.
