Which of the following is responsible for the cohesive property of water?

Question

Question restatement: The prompt asks which factor is responsible for the cohesive property of water.

Option 1: 'Covalent bonds between the hydrogen atoms of two adjacent water molecules' — This is incorrect. Water molecules do not share covalent bonds with neighboring molecules; covalent bonds occur within a single water molecule (between the oxygen and each hydrogen). Cohesion arises from interactions between separate molecules, not from intramolecular bonds.

Option 2: 'Hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule' — This is the key concept behind water's cohesion. Hydrogen bonds form between a partially negative oxygen atom of one molecule and a partially positive hydrogen atom of a neighboring molecule, linking molecules together and giving water high cohesion.

Option 3: 'Hydrogen bonds between the oxygen atoms of two adjacent water molecules' — This is inaccurate. Hydrogen bonds involve a hydrogen atom attached to an electronegative atom (like oxygen) of one molecule interacting with another electronegative atom; they do not occur directly between two oxygen atoms in this context.

Option 4: 'Covalent bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule' — This describes a covalent bond forming between molecules, which is not how water molecules interact with each other. Covalent bonds link atoms within a molecule, not separate molecules in the liquid.

Option 5: 'Hydrogen bonds between water molecules and other types of molecules' — While water can hydrogen-bond with other substances, the question specifically asks about the cohesive property of water itself, which is primarily due to water–water hydrogen bonding. Interactions with other molecules contribute to adhesion or miscibility, not cohesion.

In summary, the cohesive property of water is best explained by the presence of hydrogen bonds between the oxygen of one molecule and the hydrogen of another water molecule, which enables water molecules to stick together and exhibit strong cohesion.
