Can't a cyclic ring with 2 pi electrons be aromatic? (substituting 0 for 4n+2 rule).

Don't understand why answer c on question 66 Destroyer is wrong. Anybody?

didnt look at the question, but in addition to huckle's rule, an aromatic ring must be planar, cyclic, and have a conjugated system of pi electrons.

There's actually 4 pi electrons on there. The lone pair counts towards the pi system

If there was a posite charche instead of the negative charge, that molecule would have been aromatic.
