Quizplus · Accepted Answer

The bond between the two hydrogen atoms and the oxygen atom within each water molecule is a covalent bond. The bond between the hydrogen atom of one water molecule and the oxygen atom of another water molecule is a hydrogen bond. While hydrogen bonds are important to the structure of water and many biological molecules, they are weaker than covalent bonds. Therefore, choice C is the correct option.
