Is the ring aromatic

Four rings are described by the number of pi electrons they hold and by whether they are flat. You will apply Hückel's rule to each.

The idea. A ring is aromatic if it is flat and its number of pi electrons is $4n + 2$. A flat ring with $4n$ pi electrons is antiaromatic.

Your tasks.

1. Set fits_rule to the list of names whose number of pi electrons fits $4n + 2$, in the order of the dictionary.
2. Set aromatic to the list of names that fit the rule and are flat.
3. Set antiaromatic to the list of names that are flat and have a number of pi electrons divisible by 4.
4. Set n_naphthalene to the value of $n$ for naphthalene.
