Question

what property of a water molecule allows hydrogen bonds to form among adjacent molecules? a. the strong covalent bonds that hold the oxygen atom to each hydrogen atom b. the ionic bonds that form after the molecule separates into a hydroxide ion (oh⁻) and hydrogen ion (h⁺). c. the small size of the two hydrogen atoms compared to the oxygen atom.

Explanation:

Water is a polar molecule due to the unequal sharing of electrons between oxygen and hydrogen. Oxygen is more electronegative, creating a partial - negative charge on the oxygen atom and partial - positive charges on the hydrogen atoms. This polarity allows hydrogen bonds to form between adjacent water molecules. Covalent bonds within the water molecule are not related to hydrogen - bond formation between molecules. Water does not form ionic bonds in the context of hydrogen - bond formation between its molecules, and the size of hydrogen atoms is not the key factor for hydrogen - bond formation.

Answer:

None of the above options are correct. The correct property is the polarity of the water molecule.
