Polar molecules are the molecules:

Polar molecules are the molecules:
  1. Having zero dipole moment.
  2. Acquire a dipole moment only in the presence of electric field due to displacement of charges.
  3. Acquire a dipole moment only when magnetic field is absent.
  4. 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. ~
