Question
Chapter 7, Problem 48CP
Interpretation Introduction
Interpretation: Whether the wavelength of maximum absorption in naphthalene is shorter or longer than 255 nm that is maximum absorption in benzene needs to be determined.
Concept Introduction:Benzene shows resonance due to delocalization of
electrons. The naphthalene is formed by fusion of two benzene molecules. The structure of benzene and naphthalene is represented as follows:

I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates").
