Question

the interaction among water molecules
the figure below is depicting the interaction of water molecules with one another. the weak attractions between water molecules are known as
multiple choice
covalent bonds.
hydrogen bonds.
ionic bonds.
nonpolar interactions.
positive and negative ions.

Explanation:

• Covalent bonds are within a water molecule (between H and O), not between molecules.
• Hydrogen bonds are weak attractions between water molecules (due to the polar nature of $H_2O$, the partially positive H of one molecule is attracted to the partially negative O of another).
• Ionic bonds involve transfer of electrons (not in water - water interactions).
• Nonpolar interactions don’t apply as water is polar.
• Positive/negative ions are not the interaction between water molecules themselves. So the correct answer is hydrogen bonds.

Answer:

B. hydrogen bonds.
