Write the order of oxygen - oxygen bond energies of `O_2 ' O_3 and H_2O_2` molecules.

Explanation

To determine the order of oxygen-oxygen bond energies in the molecules O₂, O₃, and H₂O₂, we need to analyze the bond order of each molecule. The bond order is a measure of the number of chemical bonds between a pair of atoms, and it directly correlates with bond strength and bond energy.

### Step-by-Step Solution:

1. **Identify the Structure of Each Molecule:**
- **O₂ (Oxygen):** O₂ has a double bond between the two oxygen atoms.
- **O₃ (Ozone):** O₃ has a resonance structure with one double bond and one single bond, leading to a bond order of 1.5.
- **H₂O₂ (Hydrogen Peroxide):** H₂O₂ has a single bond between the two oxygen atoms.
