Absolutely...............

Explanation:

Molecular polarity is conceived to result from the VECTOR sum of the individual bond dipoles. For a molecule such as $C X_{4}$ $CX_4$ $(X = halide)$ $("X = halide")$ , the individual bond dipoles are polar, due to the difference in electronegativity between carbon and halogen. However, because the vector sum of the $C \to X$ $CrarrX$ dipoles is ZERO, the molecule is non-polar.

And thus chloroform, ${CHCl}_{3}$ $"CHCl"_3$ is polar, while ${CCl}_{4}$ $"CCl"_4$ is non-polar.
