Question 28

Hydrogen bonds bond one molecule of water with another molecule of water.

Hydrogen bonds are the type of interactions that occur between water molecules, allowing them to stick together and contribute to water's unique properties.

A) Ionic

Ionic bonds are formed through the transfer of electrons between atoms, resulting in the attraction between positively and negatively charged ions. Water molecules do not bond through ionic interactions, as they do not involve full electron transfer or the formation of charged ions.

B) Covalent

Covalent bonds involve the sharing of electron pairs between atoms, which is a characteristic of the bond within a single water molecule (between hydrogen and oxygen). However, this type of bond does not describe the interaction between separate water molecules, which is instead mediated by hydrogen bonds.

C) Hydrogen

Hydrogen bonds are the correct type of bond that forms between water molecules. In these interactions, the positively charged hydrogen atoms of one water molecule are attracted to the negatively charged oxygen atoms of another water molecule, facilitating cohesive properties.

D) Molecular

Molecular bonds refer to the general interactions between molecules but do not specify the nature of those interactions. While hydrogen bonds are a type of molecular interaction, the term "molecular" is too vague to accurately describe the specific bonding between water molecules.

Conclusion

Hydrogen bonds are essential for the unique characteristics of water and are the primary means by which water molecules interact with each other. The other options, ionic and covalent bonds, do not apply to the interaction between separate water molecules, while "molecular" lacks specificity. Thus, hydrogen bonds are clearly the definitive answer to the question.
