How do CH3Cl and CHCl3 have dipole-dipole interactions?

because cl is more electronegative it pulls the other delta positive atoms towards it. the molecules are not symmetrical, so the dipole moments do not cancel, therefore the entire molecule is polar.

The basic idea of a dipole-dipole interaction between two polar molecules is that dipole moments surrounding the central atom do not cancel each other. In this case, both CH3Cl and CHCl3 have uncancelled dipole moments because first C-H and C-Cl have different dipole moments due to different electronegativities and second CH3Cl and CHCl3 do not have exact symmetrical molecular shapes. Therefore, CH3Cl and CHCl3 can have dipole-dipole interactions with each other.
