d. Photochemical reaction: For the above molecule a photon with n=2 (enough energy to promote one electron two energy levels up) hits it, reassign the HOMO energy level, project it on the above molecule and then form the cycle with proper stereochemistry.

Question
I only need part D!!! Thank you.
a. Identify all the carbons (p-orbitals) that make up the conjugated system. Remember that these are only the carbons that contribute to the conjugated system, if there are any sp betweenp orbitals then the conjugated length is broken, and it does not contribute to the conjugated system. b. Create the MO diagram for the above molecule, remember you get one y for each p orbital that contributes to the conjugated system. Vb......second part?. Assign the HOMO and LUMO labels on the correct y. c. Form the cycle that is generated from the heating of this compound. (this is done by folding the outer most p orbitals towards each other, filled in to filled in for example) with proper stereochemistry. You may assign the substituents as R and R’is you want. d. Photochemical reaction: For the above molecule a photon with n=2 (enough energy to * promote one electron two energy levels up) hits it, reassign the HOMO energy level, project it on the above molecule and then form the cycle with proper stereochemistry.
