Liquid water is exceptional in having approximately as many hydrogen bonds as it has covalent bonds. Shown right is the number of hydrogen bonds per water molecule as the temperature rises with the line-width showing the approximate disparity between different experimental methods (data from [ 2264 ]).uch cooperativity is a fundamental property of liquid water where hydrogen bonds are up to 250% stronger than the single hydrogen bond in the dimer [ 77 ]. A strong base at the end of a chain may strengthen the bonding further.
Water molecules are able to form hydrogen bonds with C) compounds that have polar covalent bonds. Water molecules can only form hydrogen bonds between the partially positively charged hydrogen atoms in a water molecule and a partially negatively charged atom in another molecule. This means that hydrogen bonds can only form between atoms in polar covalent bonds.
