How will a polar and a non-polar molecule interact?

Solution
Dipole-induced dipole forces:
The forces operating between a polar molecule having a permanent dipole and a non-polar molecule lacking a permanent dipole are known as dipole-induced dipole forces.
It is a weak attraction that results when a polar molecule induces a dipole in an atom or in a non-polar molecule by disturbing the arrangement of electrons in the non-polar species.
The dipole–induced-dipole interaction, depends on the presence of partial charges on a polar molecule.
The presence of the partial charges of the polar molecule causes polarisation of the electron distribution of the other molecule.
