Polar molecules are the molecules: (a) having a permanent electric dipole moment (b) having zero dipole moment (c) acquire a dipole moment only in the presence of electric field due to displacement of charges (d) acquire a dipole moment only when magnetic field is absent

Answer: (a). In a polar molecule the centres of positive and negative charge do not coincide even without any external field. So it has a permanent electric dipole moment (e.g. H₂O, HCl). So the answer is (a).

Electric Dipole

Polar molecules are the molecules:

Show answer and solution

Answer: (a)

In a polar molecule the centres of positive and negative charge do not coincide even without any external field.
So it has a permanent electric dipole moment (e.g. $\text{H}_2\text{O}$ , $\text{HCl}$ ).
So the answer is (a).
