Somnath physics answered this

Dielectrics in which the center of positive charge and negative charge don’t coincide are called polar dielectrics. These dielectric molecules are of asymmetric shape. Example: NH₃, HCl, H₂O etc.

Dielectrics in which center of positive charge and negative charge coincide are called non polar dielectrics. These molecules are symmetric in shape. Example: methane, benzene, etc.

Polar Dielectrics: Polar dielectrics are those in which the possibility of center coinciding of the positive as well as negative charge is almost zero i.e. they don’t coincide with each other. The reason behind this is their shape. They all are of asymmetric shape. Some of the examples of the polar dielectrics is NH3, HCL, water etc.

Non Polar dielectrics:In case of non polar dielectrics the centres of both positive as well as negative charges coincide. Dipole moment of each molecule in non polar system is zero. All those molecules which belong to this category are symmetric in nature. Examples of non polar dielectrics are: methane , benzene etc.

Polar Dielectric

(1)The centres of positive and negative charges do not coincide because of the asymmetric

shape of the molecules.

2. It has net dipole moment in the application of external electric field.

Non-polar dielectric

(1)The centre of positive charge coincides with centre of negative charge in the molecule.

2.It has very very small dipole moment to each molecule in the application of external electric field

Aparna answered this

Polar dielectrics are the molecules whose center of the negative charge doesn’t coincide with the center of the positive charge.

Let us take the example of HCl:

The positive charge of the hydrogen atom is at its nucleus. The negative charge of the chlorine atom is orbiting at its outer most shell, the center of this orbit is somewhere near the nucleus of the chlorine atom. So, there is a finite distance between the positive nucleus of the hydrogen and the center of the negative electron of the chlorine. This constitutes a dipole, with dipole moment directed from the negative center towards the positive center.
