2021 Electrostatic Potential and CapacitanceDielectrics and Polarisation – Polar Molecules Easy Question 28 of 76 in Electrostatic Potential and Capacitance

Polar molecules are the molecules:

A acquire a dipole moment only in the presence of electric field due to displacement of charges.
B acquire a dipole moment only when magnetic field is absent.
C having a permanent electric dipole moment.
D having zero dipole moment.

The answer is C.

Solution

In polar molecules, the centres of positive and negative charges are separated by some distance even in the absence of an external field. So they have a permanent electric dipole moment.

Concept polar molecules and dipole moment
