Question

4. Oxidation and reduction (20 points total) Consider a molecule A with the following MO energies: EHOMO 2.00 eV, ELUMO =-1.00 eV. to oxidize the molecule to generate the cation A"? (A) How much energy (in eV) is minimally required Briefly explain your reasoning (B) If you use light of wavelength 266 nm to photo-oxidize A, what will be the speed of the ejected electron and what wi be its de Broglie wavelength?
