SOLVED:An approximate description of the πelectrons in conjugated polyene, CH2=CH(CH=CH) CH=CH2, is the free electron molecular orbital model. In this model, the πelectrons 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 150 pm. For butadiene and hexatriene, what are the electron configurations of the ground and first excited states in terms of particle-in-a-box eigenfunctions (see Sectio

SOLVED: Suppose that you move into an environment where the lengths ofdouble bonds become shorter. If you are studying a conjugatedpolyene (similar to the particle in a box), how will this affectthe absorbance spectrum of the polyene as compared to its normalabsorbance? Why?

SOLVED:The completely conjugated cyclic polyenones have attracted considerable interest. Consider the following aspects of their properties: a. The relative basicity of carbonyl oxygens can be measured by studying the strength of hydrogen bonding with a hydrogen donor such as phenol. The Keq for 1: 1 complexation of the following substituted cyclenones was determined. What conclusions do you draw from these data?

SOLVED:The FEMO theory (Problem 9.12 ) of conjugated molecules is crude and marginally better results are obtained with simple Hückel theory. (a) For a linear conjugated polyene with each of N carbon atoms contributing an electron in a 2 p orbital, the energies Ek of the resulting πmolecular orbitals are given by: Ek=α 2 βcos(k π)/(N 1) k=1,2,3, … N Use this expression to estimate the resonance integral βfor the series consisting of ethene, butadiene, hexatriene, and octatetraene given tha
