Choose the polar molecule from the following :

The solvents having an appreciable net dipole moment are known as polar solvents.

${\mathrm{CHCl}}_3$ is polar due the presence of a net dipole moment. There is a difference in electronegativity of the central atom, carbon, hydrogen, and chlorine. This will create a dipole in the molecule. As a dipole has formed in chloroform molecule, due to electronegativity difference, which makes it polar in nature.

Hence, option D is the answer.
