1. The problem statement, all variables and given/known data Six of the electrons from benzene C6H6 form a delocalized conjugated π-bond. We will model it as a "particle on a ring" with ring radius a, particle (electron) mass m, and "moment of inertia" I = ma2. After obtaining the energy diagram, we will fill in these 6 electrons. Please estimate the energy (in Joules) of a single delocalized π electron in the specific state shown above. Assume the radius a = 0.15 nanometers. (Hint: Just like the "quantum square" or particle in a 1-D box" problem, one can estimate the quantum number or which state from the number and structure of the nodes) 2. Relevant equations E = n2 * (h-bar)2 / (2 * I) h-bar = reduced Planck's constant = h / (2 * pi) I = ma2 3. The attempt at a solution I'm not sure where to go with this problem, I don't really understand this problem since this is one of those "extended knowledge" problems not generally covered. I know, after solving the energy formula, that each energy state n after 0 can hold 4 electrons since there is a positive and negative energy state n, and each n holds 2 electrons. Therefore on the energy level diagram, n=0 holds 2 electrons and n>0 holds four electrons. I'm pretty sure you just plug in numbers to the energy equation, but I have no idea how to determine the n's.
