Definition of hydrogen and Polar covalent bond...
Hydrogen bond
Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom (oxygen, nitrogen or fluorine) in the other molecule.
The bond inside the water molecule is polar covalent bond and bond betwen two water molecule is hydrogen bond
Polar covalent bond
Polar covalent bond is a chemical bond in which the electrons required to form a bond is unequally shared between two atoms.
The atom which is more electronegative attracts more electrons from the bonded pair than the other atom. As a result there is a slight separation of charges in a molecule in which more electronegative atom (comparatively) carries a slight negative charge and less electronegative atom carries a positive charge. The bonds formed between two atoms have a permanent electric dipole.
