explain me hydrogen bonding in ice and warer ?
Answers
Answer:
In liquid water each molecule is hydrogen bonded to approximately 3.4 other water molecules. In ice each each molecule is hydrogen bonded to 4 other molecules. ... In ice Ih, each water forms four hydrogen bonds with O---O distances of 2.76 Angstroms to the nearest oxygen neighbor.
Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule; generally, a proton shared by two lone electron pairs. ... Hence, the oxygen atom is partially negatively charged, and the hydrogen atom is partially positively charged.

Hydrogen bonds in water provide many characteristic benefits to water: cohesion (holding water molecules together), high specific heat (absorbing heat when breaking, releasing heat when forming; minimizing temperature change), high heat of vaporization (several hydrogen bonds must be broken in order to evaporate water)
