Covalent Bond Strength
Captions available
The idea
A covalent bond's strength is measured by its bond dissociation energy, the energy required to break one mole of that bond in the gas phase.
In practice
A carbon-carbon triple bond's dissociation energy exceeds a carbon-carbon single bond's, matching the triple bond's shorter length.
Where people slip
Bond dissociation energy is defined for breaking a bond, absorbing energy — forming that same bond releases the identical amount.
