Study Notes
Hydrogen Bonds
- Hydrogen bonds are special attractions between a hydrogen atom and a highly electronegative atom.
- They are weaker than covalent or ionic bonds.
Importance of Hydrogen Bonds
- Hydrogen bonds hold together the two strands of DNA, allowing it to store and transmit genetic information.
- Hydrogen bonds in water contribute to its high boiling point and surface tension.
Hydrogen Bonds in Various Substances
Hydrogen Fluoride
- Hydrogen fluoride is able to act as a strong acid due to its ability to form strong hydrogen bonds.
Ammonia
- The high boiling point of ammonia is due in part to the hydrogen bonding between its molecules.
Summary
- Hydrogen bonds are weak, but have a big impact on the properties of many substances.
- They are the invisible force holding together the building blocks of life, and contribute to the unique properties of many substances.
