June 2023 NY Regents Chemistry Exam
17 Which statement explains the low boiling point of hydrogen, H2, at standard pressure? (1) Hydrogen has strong covalent bonds. (2) Hydrogen has weak covalent bonds. (3) Hydrogen has strong intermolecular forces.
(4) Hydrogen has weak intermolecular forces.
Solution: The stronger the intermolecular forces, the higher the boiling point of a substance. Since, H2 has a low boiling point, it must have weak intermolecular forces.
