Problem 3 The carboncarbon bond length in benzene is 1.39 A. Assuming that the circumference of the 7relectron \"ring\" in benzene is six times this distance, and that the 7r electrons can be treated by the particleonaring model, estimate the wavelength of light needed to promote an electron from the highestoccupied to the lowestunoccupied energy level. Compare to the experimental wavelength of 203.8 nm
