What is the most important role of hydrogen bonding between water molecules

Answer 1

The most important role of hydrogen bonding between water molecules is its contribution to the unique properties of water. Hydrogen bonding gives water its high boiling point, high specific heat capacity, and high heat of vaporization, which are crucial for maintaining stable temperatures on Earth and allow water to exist in all three states (solid, liquid, and gas) within a relatively narrow range of temperatures. Hydrogen bonding also gives water its cohesive and adhesive properties, allowing it to be an excellent solvent and facilitating transportation of nutrients and waste in biological systems. Additionally, hydrogen bonding between water molecules results in surface tension, allowing insects to walk on water and water to bead up on surfaces.
