WebThe polarity of water allows it to form hydrogen bonds, a stronger version of the usual dipole-dipole intermolecular force (and NOT a type of covalent or ionic bond as its name might imply). Hydrogen bonding occurs between a partially positive H atom (usually bonded to an N, O, or F atom) of one molecule and a partially negative atom (usually N ... 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. moshe ettedgui
