The partial negative charge at one end of a water molecule is attracted to the partial positive charge of another water molecule. What is this attraction called?
A) a covalent bond
B) a hydrogen bond
C) an ionic bond
D) a van der Waals interaction

Question

Quizplus · Accepted Answer

The attraction between the partial negative charge of one water molecule and the partial positive charge of another water molecule is called a hydrogen bond. This type of bond is weaker than a covalent bond or an ionic bond, but it is important for many biological processes, including the structure of DNA and the folding of proteins. Van der Waals interactions are also weak, non-covalent attractions between molecules, but they are not specific to water molecules.
