Calculate the energy levels of the -network in hexatriene, C 6 H 8 , using the particle

Calculate the energy levels of the π-network in hexatriene, C₆H₈, using the particle in the box model. To calculate the box length, assume that the molecule is linear and use the values 135 and 154 pm for C=C and C - C bonds. What is the wavelength of light required to induce a transition from the ground state to the first excited state? How does this compare with the experimentally observed value of 240 nm? What does the comparison made suggest to you about estimating the length of the π-network by adding bond lengths for this molecule?
