What is the strongest evidence for hydrogen
bonding?
1. Hydrogen has an extremely low electronegativity.
2. The boiling points of NH3, H2O, and HF
are abnormally high compared with the rest
of the hydrides in their respective periods.
3. Hydrogen can be considered either a
metal or nonmetal.
4. Hydrogen is able to accept or donate electrons, so it is the most versatile atom in the
periodic chart.
