Question restatement: The prompt asks about the type of bond formed between two water molecules. Answer options presented are: hydrogen bond, Van der Waals bond, covalent bond, polar covalent bond, ionic bond.
Option 1: hydrogen bond. This is the correct description for the intermolecular attraction that occurs between the partial positive hydrogen atom of one water molecule and the partial negative oxygen atom of another water molecule. It is weaker than covalent bonds but essential for properties like high boiling point and cohesion in water.
Option 2: Van der Waals bond. While water molecules do experience Van der Waals forces with nearby molecules, the specific and directional bond that holds two water molecules together in the liquid state is better described as a hydrogen bond, not a generic Van der Waals interaction.
Option 3: covalent bond. A covalent bond involves sharing electron pairs between atoms within a molecule. In H2O, the O–H bonds within a single molecule are covalent, but the interaction between two separate water molecules is not a covalent bond.
Option 4: polar covalent bond. This term describes the type of bond within a molecule where electrons are shared unequally between atoms of different electronegativities; in water, the O–H bonds are indeed polar covalent. However, the intermolecular force between two distinct water molecules is not a polar covalent bond.
Option 5: ionic bond. Ionic bonds arise from transfer of electrons and the attraction between oppositely charged ions. Water molecules interact via hydrogen bonding rather than forming ionic bonds between molecules.
