WebWater is a liquid at room temperature because hydrogen bonds between water molecules provide enough cohesive force to hold them together. Polar substances dissolve readily in water because they can replace energetically favorable water-water interactions with even more favorable water solute interactions. Web24 dec. 2024 · Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength. The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond. Hydrogen bonds are responsible for holding together DNA, proteins, and other macromolecules.
