A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.
Ionic bond is formed when there is complete transfer of electron from one atom to another atom.
Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.
Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom by sharing of electrons and thus form polar covalent bonds.
