What kind of intermolecular forces act between a chloroacetylene c2hcl molecule and a dichloroethylene ch2ccl2 molecule?

dipole-dipole

Explanation:

There are essentially four types of intermolecular forces that exists between molecules. These include:

Ionic > hydrogen bonding > dipole-dipole > london dispersion

Ionic forces are the strongest while london dispersion forces which are weak Van der waals forces are the weakest

In the given examples, chlorine the most electronegative atom relative to C and H. Both molecules are polar and have dipoles. Thus, dipole-dipole forces exits between these molecules.
