Polar molecules are the molecules :

Question

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.

Doubtly AI · Accepted Answer

Answer: 4. having a permanent electric dipole moment. Polar molecules (such as H₂O , HCl) have centres of positive and negative charge that do not coincide, so they have a permanent dipole moment. Option 4. Option 1 describes non-polar molecules, and option 2 describes non-polar molecules that get an induced dipole in a field.
