Answer: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.
Example: A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms.
