Verified step by step guidance

Understand the nature of water molecules: Water (H₂O) is a polar molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other.

Identify the types of bonds: Covalent bonds involve the sharing of electrons between atoms, ionic bonds involve the transfer of electrons, and hydrogen bonds are weak attractions between a hydrogen atom and an electronegative atom.

Recognize the structure of water: Each water molecule has two hydrogen atoms covalently bonded to one oxygen atom, creating a bent shape with a partial negative charge near the oxygen and a partial positive charge near the hydrogens.

Determine the interaction between water molecules: The partial positive charge of the hydrogen atoms in one water molecule is attracted to the partial negative charge of the oxygen atom in another water molecule.

Conclude the type of bond: This attraction between the hydrogen of one water molecule and the oxygen of another is known as a hydrogen bond, which is responsible for many of water's unique properties.
