Question

which has more bond dissociation energy&why.
O2+ or O2 ?

Answer 1

O2+ has more bond dissociation energy than O2.

Because the bond order in O2 is 2 where as in O2+ is 2.5.If bond order is more energy required to break the bonds is more.


To calculate the bond order we should see the molecular orbital diagram.

Answer 2

Answer:

The bond energy of O₂⁺ is higher than that of O₂. This is because the bond order O₂⁺ is more than that of O₂.

Explanation:

The bond energy of O₂⁺ is higher than that of O₂. This is due to the fact that the bond order in O₂ is 2, but it is 2.5 in O₂⁺.

The bond energy is exactly proportional to the molecule's bond order.

If the bond order is higher, it takes more energy to break the bonds.

The bond order refers to the number of bonds that exist between two atoms in a molecule.

Bond dissociation energy is the amount of energy necessary to break one mole of identical bonds in order to separate the bonded atoms in the gaseous state.
