Question 13

Chemical Bonding

Water has a rather high boiling point despite its low molecular mass because of the presence of

  1. A.hydrogen bonding
  2. B.covalent bonding
  3. C.ionic bonding
  4. D.metallic bonding
Show the answer and explanation

Answer: A (hydrogen bonding)

Explanation

Water molecules are held together by strong hydrogen bonds, which need extra energy to break, so water boils at 100°C instead of far lower.
