           -second smallest difference

           -Third smallest difference

           -Largest difference

**HOMO and LUMO**

The image displays four chemical structures labeled A, B, C, and D. 

- **Structure A**: Features a zigzag chain with a branched double bond.
- **Structure B**: Consists of a straight chain of alternating single and double bonds, indicating a conjugated system.
- **Structure C**: Contains a five-membered aromatic ring connected to a conjugated chain with alternating single and double bonds.
- **Structure D**: Includes a six-membered aromatic ring attached to a similar conjugated chain as seen in structure B.

These structures are examples used to explore concepts related to Highest Occupied Molecular Orbitals (HOMO) and Lowest Unoccupied Molecular Orbitals (LUMO) in conjugated systems. The examination of these orbitals helps in understanding chemical reactivity and properties of molecules.
