Question

Quizplus · Accepted Answer

When a molecule dissolves in water, hydrogen bonds often form between the molecule and water. This is because water is a polar solvent, and its partial positive (hydrogen) and partial negative (oxygen) ends can interact with other polar molecules or ions, leading to the formation of hydrogen bonds. This interaction is crucial for the dissolution process but does not involve breaking or forming covalent bonds within the water or the solute molecule.
