CH4 is tetrahedral and the electronegativity of H is constant for all H's. Therefore it is symmetric and net electons will be distributed evenly between all H's..
The electronegativity of Cl, is not the same as H, which means that Cl will pull the electron cloud to one side of the molecule, thereby making one part of the molecule appear more negative, and one part of the molecule appear more positive. This is what is meant by a polar molecule.

Wow.. That is an IIT level question. It is also predominantly asked in AIEEE too..
Well, the answer is because in Methane, it acquires symmetry structure. dipole moment is zero, where as in the other one, this is not so.
I will check in my notes, and get back to you, if my answer is not correct..
Well, I have checked it.. and the answer above my answer is correct. My professor has given exactly the same notes...
