Polar and Non-Polar Molecules
When multiple atoms are bonded to each other, a molecule is formed. These bonds or electron sharing arrangement can be polar( when electrons are shared unequally) and non-polar( when electrons are shared equally).

Various substances may have polar and non-polar molecules depending upon the charge configuration inside them. A substance can be polarized from an external electric field which leads to development of induced dipole moment inside them.
