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)
A mixture of 1.07 g H2 and 1.50 g He is placed in a 1.00-L container at 30.°C. Calculate the partial pressure of each gas and the total pressure.
