Question

When is bond energy equal to bond dissociation energy???is bond dissociation energy equal to bond energy of all covalent molecules

Answer 1

Answer:

Bond dissociation energy is only equal to bond energy for diatomic molecules. This is because the bond dissociation energy is the energy of a single chemical bond, while bond energy is the average value for all the bond dissociation energies of all bonds of a certain type within a molecule.
