WebD) The electrostatic attraction between ions is weakened by the specific heat of water. E) The electrostatic attraction between ions is weakened by the cohesive properties of water., Hydrogen bonds form between neighboring water molecules because of: A) the viscosity of water. B) electron sharing. C) electron transfer. D) surface tension. WebAug 27, 2024 · H-bonding occurs in water. In the liquid state they are rapidly being formed and broken as the mobile particles move over each other. Note in figure 11.5.2 that there are two type of O-H bonds, the intramolecular O-H bond within a molecule (bond length = 1.01Å) and the intermolecular bond between atoms (bond length = 1.75Å).
