Explain the accurate solution of the given question
Question- Naphthalene has 10 pi electrons that can be delocalized over the molecule. As a crude model of the electronic motion, we can consider these 10 electrons to be moving freely in 2-dimensional rectangular box 3 angstroms by 6 angstroms. (Each benzene ring is considered to be 3 angstroms by 3 angstroms square)
Part 1- Draw an energy level diagram showing the first 6 energy levels laeling the states with their quantum numbers.
Part 2- What energy does the ground state (counting all 10 electrons) have?
I want help to draw an energy level diagram.
