How many resonance forms can be drawn for a molecule of tetracene?
The first three linearly fused polycycllic aromatic hydrocarbons are naphthalene (2 rings), anthracene (3 rings), and tetracene (4 rings). How many resonance forms can be drawn for a molecule of tetracene?

The best help would be to ask what the words, "resonance forms", mean. For example, are there two forms of benzene where the double bonds flip back and forth? Or is there only one where the pi cloud is delocalized over all six carbons? The two forms with the static double and single bonds are easier to draw than the one form with the single-and-a-half bonds. Which is the best representation of reality?
