Answer

Answer:

Water molecules are polar.

Brief Explanations:

Hydrogen bonds form between polar molecules. Water ((H_2O)) has a bent shape. Oxygen is more electronegative than hydrogen. So, electrons are pulled closer to oxygen, creating a partial negative charge ((\delta -)) on oxygen and partial positive charges ((\delta +)) on hydrogens. This polarity allows the (\delta +) (on (H) of one (H_2O)) to be attracted to the (\delta -) (on (O) of another (H_2O)), forming hydrogen bonds.

  • Water molecule atoms have strong covalent bonds (not weak atomic bonds), so that option is incorrect.
  • Adhesion is the attraction between different substances. Here we are talking about attraction between water molecules (co - attraction due to hydrogen bonds), so the adhesion option is not relevant.
  • Water molecules ((H_2O)) are small ((M = 18g/mol)), so the “water molecules are large” option is wrong.
