Polar molecules are the molecules:

Options

  1. AHaving zero dipole moment.
  2. BAcquire a dipole moment only in the presence of electric field due to displacement of charges.
  3. CAcquire a dipole moment only when magnetic field is absent.
  4. DHaving a permanent electric dipole moment.

Correct answer

D. Having a permanent electric dipole moment.

Step-by-step 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.
