Polar molecule

The substance which are made up of such molecules, whose positive and negative charge centers are different, then the substances made up of such molecules are called polar substances and the molecule are called polar molecules.
These molecules are responsible for the flow of electric current in the substance.

Example
HCl
NaCl

Non polar molecule

Such molecule in which positive and negative charges are concentrated at the same point,
ie,
There is no space between the point and negative charges.
The substance formed by non-polar molecules is called non-polar molecules.
These substance are bad conductors of electricity.

Example
H₂, N₂, H₂O etc.
