Why is CHCl3 a polar molecule?

Answer 1

Molecular geometery is tetrahedral now look below Cl l H-C-Cl l Cl Now if you look at it you need to find of the geometry has a dipole moment, if it does then that means that it is polar. Well the clorines have the same electronegativity, so there pull on each other will cancel each other out. Now look at the H Cl Hydrogen has a less electronegativity than Clorine so its gonna pull the electrons from the H to the clorine resulting in a pull of the toward the Cl meaning it is polar. Consider carbon tetracloride CCl4 is that polar or non-polar, you might be able to use what I said to find the answer.
