What type of bond forms between water molecules?

Water molecules are known for forming hydrogen bonds, which are a type of weak intermolecular force that occurs between the hydrogen atom of one water molecule and the oxygen atom of another water molecule. This bonding results from the polarity of water, where the oxygen atom is slightly negatively charged and the hydrogen atoms are slightly positively charged.

The hydrogen bond is crucial for many properties of water, such as its high boiling point, surface tension, and ability to dissolve many substances. The ability of water to form hydrogen bonds leads to its unique behaviors in different temperatures and conditions, making it essential for life.

While ionic bonds are formed through the complete transfer of electrons from one atom to another, and covalent bonds involve the sharing of electron pairs, neither of these types is responsible for the interaction between water molecules. Additionally, a polar bond refers to the covalent bond between atoms with different electronegativities, such as the bonds within a water molecule itself, but does not categorize the interaction between separate water molecules. Therefore, the hydrogen bond is the correct type of bond that forms between water molecules.
