Question 2 [35\%]: Consider the conjugated double bond system in the molecule shown below. a) (10\%) Draw \( \Pi \) orbital diagram for the above molecule. b) \( (5 \%) \) Determine the values of the quantum numbers \( (\mathrm{n}) \) for the HOMO and the LUMO orbitals. c) \( (\mathbf{1 0} \% \) ) Consider average carbon - carbon bond length equal to \( 1.21 \AA \). Calculate the energy difference between HOMO and LUMO orbitals (in eV). d) (10\%) Calculate the wavelength of light (in \( \mathrm{nm} \) ) needed to induce HOMO-LUMO transition.
