How Is Bond Energy Measured and What Techniques Are Used in Its Determination?

Bond energy is the amount of energy needed to break one mole of a bond in a gas. It's usually measured in kilojoules per mole, or kJ/mol.

How Bond Energy is Measured:

  1. Calorimetry:

    • Scientists look at burning reactions to study energy changes. This helps them figure out bond energies.

  2. Spectroscopy:

    • Tools like Infrared (IR) and Nuclear Magnetic Resonance (NMR) spectroscopy help us understand how molecules move and vibrate. This information is useful for calculating bond energy.

Some Numbers to Know:

  • The energy of a C–C bond is about 348 kJ/mol.
  • An O–H bond has an energy of around 463 kJ/mol.
  • Bonds that are stronger need more energy to break, showing that the molecules are more stable.
