Alarge value for bond energy corresponds to a more (stable/unstable) molecule, which corresponds to a (lower/higher) energy state

Explanation:

More is the bond order more will be the overlapping taking place between the atoms of a molecule.

As a result, more strong the bond will be and this also means that more will bond energy. Hence, the compound formed will be stable in nature.

Now, the relation between energy state and stability is as follows.

Hence, more stable is the compound lesser will be its energy state.

Thus, we can conclude that a large value for bond energy corresponds to a more stable molecule, which corresponds to a lower energy state.
