Q112 / 200 · NEET 2021 · Physics

Polar molecules are the molecules:

A
Having zero dipole moment.
B
Acquire a dipole moment only in the presence of electric field due to displacement of charges.
C
Acquire a dipole moment only when magnetic field is absent.
Correct answer
D
Having a permanent electric dipole moment.

Solution

A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. Therefore, these molecules have permanent electric dipole moment.

Hence, the correct answer is option: 'D'.
