Polar molecules are the molecules:

  1. A
    Acquire a dipole moment only when magnetic field is absent.
  2. B
    Having a permanent electric dipole moment.
  3. C
    Having zero dipole moment.
  4. D
    presence of electric field due to displacement of charges.

Solution & Step-by-step Explanation

Polar molecules are those in which the center of positive charge and the center of negative charge do not coincide, even in the absence of an external electric field. This results in a permanent electric dipole moment.
