Question

laims compliance with the PDF/A standard and has been opened read-only to prevent modification Er An approximated description of the π electrons in conjugated polyene, CH2-CH(CH-CH)CH-CH2 is the free electron molecular orbital model. In this model, the t electrons are assumed to be noninteracting and to be in a one- dimensional box of length equal to one less than the number of carbons multiplied by the C-C distance of 150pm. For butadiene, what are the electron configurations of the ground and first excited states in terms of particle-in-a-box eigenfucntions? What is the excitation energy from the ground to the first excited state? What is the wavelength of this transition? enoVO F5 F6 F7 F8 F10 F11
