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 .
