The energy levels for the particle-in-a-box model can be used to predict the energy required to excite an electron that is part of a conjugated systems. The electron is essentially a particle that is trapped in the conjugated system. Butadiene has 4 electrons that are part of the conjugated system, which, in the lowest energy conformation, can be considered to be in two energy levels (1 and 2). n H H H 133.8 pm # 145.4 pm 133.8 pm H -H H # H Calculate the wavelength of light (nm) needed to promote an electron from n=2 to n=3. Hint: To first determine L, use the three bond lengths plus the distance equal to a C atom radius at each end (77 pm). (50 (210 () 460 (600 780 Energy 2
