Hydrogen bond between two water molecules

WebWater: Hydrogen-bonding network Hydrogen bonds are found between molecules of water and molecules of ammonia. They are defined as the attractive interaction between a hydrogen atom bonded to a very electronegative atom (O, N, or F) and an unshared electron pair on another electronegative atom. Liquid water contains a vast three … WebIn a water molecule, electronegative oxygen atom attracts hydrogen electrons resulting in the formation of a partial negative charge on oxygen atom and a partially positive charge on a hydrogen atom. As a result, a water molecule is a dipole. This feature leads to the formation of hydrogen bonds between partially charged water molecules.
