Introduced to this in AP Chemistry
What is it?
The enthalpy change required to break a covalent bond in one mole of gaseous molecules is the bond energy
Ayush term:
As bonds occur either by sharing or transferring it’s because it achieves a noble gas configuration which makes it stable
Creating of a bond is exothermic
Breaking of a bond is endothermic
General Rule: Single Bond < Double Bond < Triple Bond
Another way to find Enthalpy of Formation:
H = n BE (broken) - n BE (formed) Sum of number of broken molecules * Bond energy - Sum of number of formed molecules * Bond Energy
- n = moles of broken molecules
- BE = bond energy
