CHCL3 is polar because there are 3 chlorines and 1 hydrogen evenly spaced around carbon. Chlorine is highly electronegative; it pulls electrons from other atoms in molecules. Chlorine-Chlorine cancels out, but the H-C-Cl bond, Chlorine is across from hydrogen and pulls its electron, causing polarity with electrons centered around chlorine.
