  Each water molecule is joined to four other water molecules by hydrogen bonds.

Explanation:  As we know that the hydrogen bonding is a type of bonding in which the hydrogen attached to the electronegative atom of one molecule makes electrostatic forces of attraction with the electronegative atom of the other molecule.

Thus hydrogen which is attached to the electronegative oxygen atom will make a bond with the oxygen atom of the other molecule of water . Thus four types of binds can be formed with the one molecule of the water.
