4.) \( 1,3,5 \)-Hexatriene is a conjugated triene molecule containing 6 carbon atoms. Consider an electron behaving as a particle in a box and is able to travel along \( x=0 \) and \( x=L \), where \( L \) is the length of the molecule. a.) If the absorption occurs at the wavelength of \( 256 \mathrm{~nm} \) for 1,3,5-Hexatriene for an electronic transition of the pi-electron from the highest occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO), determine the length of the molecule. (5 pts). b.) Normalize the wavefunction and determine the probability of finding the electron in the HOMO within \( x=0.40 \mathrm{~L} \) to \( \mathrm{x}=0.60 \mathrm{~L} \). (10 pts) c.) Determine the average momentum and position of the electron located at the HOMO. (10 pts) d.) Show that the wavefunction of the electron at the HOMO and LUMO are orthogonal with each other. (5 pts)
