1. How To Draw a Free Electron Model Energy Level Scheme for Hexatriene, give correct energy assignment and quantum number and include correct spin

2. Apply the particle in a box to the pi electrons in hexatriene and predict the first electronic transition and

3, does hexatriene absorb in the visible spectrum? (Show all work)

I was going along the lines of having number 1 be like because there are 6 pi electrons with opposite spins

n=2 -o-o-

n=1 -o-o-

ground -o-o-

2. delta E = (H^2)/(8mL) with h = 6.626 x 10^-34 m = mass of an electron and L being 135 x 10^ -12m (being the length but dont know where to go with this of the carbon double bond

3. Need to solve for delta E to use the equation : Lambda = (hc) / (delta E)
