Here are the essential concepts you must grasp in order to answer the question correctly.
Conjugated Dienes
Conjugated dienes are organic compounds that contain two double bonds separated by a single bond. This arrangement allows for delocalization of π electrons across the double bonds, which can enhance stability and reactivity. Understanding the structure and behavior of conjugated dienes is crucial for predicting their chemical properties and reactions.

HOMO and LUMO
HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital) are key concepts in molecular orbital theory. The HOMO is the highest energy orbital that contains electrons, while the LUMO is the lowest energy orbital that is empty. The symmetry and energy of these orbitals play a significant role in determining the reactivity of molecules, particularly in reactions involving electron transfer.

Symmetry in Molecular Orbitals
Symmetry in molecular orbitals refers to the spatial arrangement and behavior of electrons within those orbitals. A symmetric HOMO indicates that the electron density is evenly distributed, which can influence the molecule's reactivity and interaction with other species. In the case of conjugated dienes, the symmetry of the HOMO can vary depending on the number of double bonds and their arrangement, affecting the overall electronic properties of the molecule.
