Question
What are polar dielectrics and non polar dielectrics
✓
Answer
polar dielectrics:
1. A dielectric molecule in which the centre of mass of positive charges (protons) does not coincide with the centre of mass of negative charges (electrons) because the asymmetric shape of the molecules is called a polar dielectric.
2.Representation:
3.They have permanent dipole moments of the order of $10^{–30} cm$. They act as tiny electric dipoles, as the charges are separated by a small distance.
4.Examples: $HCl, water, alcohol, NH_3$ etc.
nonpolar dielectric:
1.A dielectric in which the centre of mass of the positive charges coincides with the centre of mass of the negative charges is called a non-polar dielectric.
2.Representation:
3.These have symmetrical shapes and have zero dipole moments in the normal state.
4.Examples: $H_2, N_2, O_2, CO_2$, benzene, methane.
